View GrainGage Info

On the Setup > H2 or H3 GrainGage screen,

Tap Info.

Mirus opens the Info screen on which you can view Chamber, Module, and Sensor information for the GrainGage.

Configure Weight Sensors

On the Setup > H2 or H3 GrainGage screen,

Tap Sensors > Weight.

Mirus opens the Weight Sensors Setup screen on which you can configure weigh bucket settings for the GrainGage.

The following table displays the typical preferred setting for each item on this screen.

Weight Sensors Settings
Setup Parameter	Default Value	Description
Chamber Head Room	25%	The percentage of additional grain required to perform a moisture and test weight measurement or include that sub-cycles as part of the average moisture and test weight measurement. For example, if the chamber head room is set to 25% and the minimum weight threshold is 4 lb, then Mirus requires 5 lb to ensure that the test chamber is full and that the data will be accurate. If the full amount isn’t reached (i.e., minimum weight threshold + chamber head room), Mirus doesn’t record the moisture or test weight data, because it’s not likely to be accurate. Mirus still collects the plot weight. If the amount required by Mirus isn’t met on a sub-cycle, then that moisture and test weight measurement won’t be included in calculating the average. If you are harvesting low yield grains, the chamber head room can be set as low as 15% without losing any accuracy.
Evacuation Time	2000 msec	The amount of time all the top and bottom gates remain open to allow for the evacuation of all grain from the weigh bucket. This setting overrides the open state time for the top and bottom gates. Caution: Wetter grain or oil seeds may require longer evacuation times. Low-volume inserts will also require a longer evacuation time. If this setting is inaccurate, it may increase the weighing cycle time unnecessarily or cause the mixing of two plots.
Load Cell Coefficients	2.000	The default values for load cell coefficients are placeholders. These are custom values that are generated during weight calibration. They are used to convert millivolt readings from the load cells into pounds or kilograms. Do not adjust these manually.
Slope and Motion Compensation	Yes	This corrects weight errors resulting from movement and vibration as well as harvesting on a slope.
Trip Point	80%	The percentage of full bucket capacity at which a weight trip cycle will occur.
Weigh Time	1000 msec	The period over which weight readings are averaged. Although a shorter weigh time will shorten cycle times, it may reduce the accuracy of the measurement.
Weight Tare Warning	0.500 lb (0.227 kg)	This is the threshold above which a tare warning is generated after weigh bucket evacuation.

Note: Preconfigured values are default values based on generalized harvest conditions. They may not reflect the optimum settings for the harvest conditions for your particular climate, fields, or grains. Changing default values requires a certain level of experience. Please contact HarvestMaster Field Service Engineers when adjusting these settings. See Contact a HarvestMaster Field Service Engineer.

Configure Test Weight Sensors

On the Setup > H2 or H3 GrainGage > Sensors screen,

Tap Test Weight.

Mirus opens the Test Weight Sensor Setup screen on which you can configure test weight settings for the GrainGage.

Test Weight Sensor Settings
Setup Parameter	Default Value	Description
Test Weight Tare Warning	2.02 lb/bu 2.6 kg/hL	A tare warning is generated when a tare check indicates weight in the chamber is above this threshold.

Note: To edit other test weight settings, see Calibrate Test Weight.

Configure Moisture Sensors

Note: This option is only available with the H2 GrainGage.

On the Setup > H2 GrainGage > Sensors screen,

Tap Moisture.

Mirus opens the Moisture Sensor Setup screen where you can configure the moisture setting for the GrainGage.

Moisture Sensor Settings
Setup Parameter	Default Value	Description
Moisture Tare Warning	1%	A tare warning is generated when a tare check indicates that the moisture is above this threshold.

Note: To edit other moisture settings, see M2.0 Moisture Model Recalibration.

Configure Overflow Sensor

Go to the Setup > H2 or H3 GrainGage > Sensors screen.

Tap Level Detect.

Mirus opens the Level Detect Sensors Setup screen on which you can configure Level Clear Delay and enable/disable the Overflow Sensor.

Note: Typically, only H2 or H3 Classics mounted on Wintersteiger Quantum or Classic Plus combines are equipped with an overflow sensor that trips when grain is in close proximity.

Level Detect Sensor Settings
Setup Parameter	Default Value	Description
Level Clear Delay	1000 msec	The amount of time delay between last level/weight trip and the start of the flush cycle.
Overflow Sensor	Yes	Enables the sensor for use in overflow detection.

Configure the GrainGage System Settings

On the Setup > H2 or H3 GrainGage screen,

Tap System.

Mirus opens the System Setup screen where you can configure settings for the GrainGage.

The following table displays the typical preferred setting for each item on this screen.

System Settings
Item	Default Value	Description
Debug Streaming Enabled	Yes	This enables or disables debug streaming messages for the DSP module. HarvestMaster recommends leaving this enabled.
GrainGage Type	Classic	Designates which GrainGage type is connected to Mirus.
Isolation Gate Mode	Normally Open	Controls the initial state of the isolation gate.
Max Sub-Cycle Count	1	The maximum number of sub-cycles that will be run during a cycle if the minimum weight threshold continues to be satisfied.
Enable SCiO Data Sync	Yes	H3 SCiO scan data will be backed up to the cloud upon connecting to the internet.

Reset the GrainGage to Factory Settings

This option can be found on the Setup > H2 or H3 GrainGage > Factory Reset screen.

CAUTION: This cannot be undone! Resetting the GrainGage to factory defaults will clear all your settings, including actuator timers and weight calibrations. This should only be done in consultation with a HarvestMaster Field Service Engineer.

Update the GrainGage Firmware

This option can be found on the Setup > H2 or H3 GrainGage > Firmware screen.

As an operator, you are not likely to need this screen. When you install or update Mirus, the program will check for the latest firmware and update it automatically. The purpose of this screen is to help HarvestMaster Field Service Engineers during troubleshooting procedures.

The moisture curve option is covered in detail in Moisture Curve and Chamber Calibration Wizard.

Export SCiO Files

This option can be found on the Setup > H3 GrainGage > SCiO screen.

You can zip the raw scan files that could be used for post-processing here if needed.

Create and Record Traits

This option can be found on the Setup screen.

To create a new trait,

Tap the new icon .
Enter a Name and Description for the new trait.
Select the Type of trait.
Select when you want Mirus to prompt the operator to record the trait: Before Plot or After Plot.
Specify the Length, or number of characters allowed in the record field.
Indicate whether or not this trait is Repetitive.
Enter the Default Value (if needed).
Tap the next arrow to save the trait.

The following table describes the settings for each item on this screen.

New Trait Settings
Item	Description
Name	This is the name of the trait.
Description	This describes the type of data to be recorded within the trait.
Type	Text: A text trait allows the user to record text relative to the individual plot. You can set a character limit (Length) and/or a Default Value for quick selection. Number: A number trait allows the user to record a number (e.g., a score) relative to an individual plot. You can set a character limit (Length) and/or a Default Value for quick selection. List: A list trait allows the user to select a value from a list of options. The list is created by entering the values in the Default Value field. To add multiple values, tap the plus icon on the right side of the window. This feature functions best when selecting from no more than five different trait values. Date: A date trait records dates. The Default Value is the current date, but a user may select a different date.
Harvest Collection Time	Specifies whether trait data will be collected before or after the plot is harvested.
Length	This setting helps Mirus know when to move on to the next trait. After the allotted number of characters is entered, Mirus moves on automatically so that the operator doesn’t need to press enter.
Repetitive	Selecting “Yes” indicates data for that trait will be collected multiple times on different days. For example, if you wanted to rate your grain for disease three times a year, you would have a repetitive disease trait.
Default Value	This is the most common or most expected value for this trait. Mirus will automatically populate the record field with this value to save the operator time. The operator needs only to press or tap Enter. If the value is different from the default value, the operator can enter the new value and press Enter. If the maximum number of characters within the length of the trait is met, Mirus will advance automatically.
