Introduction
The AgraTronix MT-16 Grain Moisture Tester is a precision instrument designed for accurately measuring the moisture content of various grain types. It provides direct readout for 16 different grain scales, with each scale being adjustable to match local elevator readings. The device features a high-frequency, capacitive circuit for improved accuracy and can automatically average up to 99 test results. A convenient carrying case with a shoulder strap is included for portability and protection.
Safety Information
- Always handle the device with care to prevent damage to internal components.
- Do not expose the tester to extreme temperatures or direct moisture, beyond its operational range.
- Ensure the battery compartment is securely closed to prevent dust or moisture ingress.
- Keep the device out of reach of children.
- Use only the specified battery type (9V) for operation.

Setup
Battery Installation
- Locate the battery compartment on the back or bottom of the MT-16 tester.
- Open the battery compartment cover.
- Insert one 9V battery, ensuring correct polarity (+/-).
- Close the battery compartment cover securely.
Operating Instructions
Basic Operation
- Power On: Press the 'Power' button (P) to turn on the device. The display will illuminate.
- Select Grain Type: Use the 'Function' button (F) to cycle through the available grain scales until the desired grain type is displayed.
- Prepare Sample: Fill the grain sample chamber with the grain to be tested, ensuring it is level with the top of the chamber.
- Take Reading: The tester will automatically measure the moisture content. The result will be displayed on the screen.
- Power Off: Press and hold the 'Power' button (P) to turn off the device when testing is complete.
Grain Scale Selection and Adjustment
The MT-16 offers direct readout for 16 different grain scales, including Corn (5-21%, 17-40%), Wheat-soft, Wheat-hard, Soybeans, Sorghum, Oats, Canola, Barley, Rye, Beans Paddy Rice, Flax, Safflower, Sunflower-oilseed, Sunflower-confect, and an Arbitrary Scale. Each scale can be adjusted to match readings from local elevators for improved accuracy. Refer to the device's internal menu or specific instructions for calibration procedures.
Averaging Test Results
The MT-16 can automatically average up to 99 test results. This feature helps to provide a more reliable and representative moisture content reading, especially when testing heterogeneous samples. Consult the device's on-screen prompts or specific instructions for initiating and viewing averaged results.
Maintenance
Cleaning
- After each use, especially when changing grain types, ensure the sample chamber is free of residual grain or dust.
- Use a soft, dry cloth to wipe the exterior of the device.
- Do not use abrasive cleaners or immerse the device in water.
Storage
- Store the MT-16 in its provided carrying case when not in use to protect it from dust and physical damage.
- Store in a cool, dry place, away from direct sunlight and extreme temperatures.
- If storing for an extended period, remove the 9V battery to prevent leakage.
Troubleshooting
| Problem | Possible Cause | Solution |
|---|---|---|
| Device does not power on | Dead or incorrectly installed battery | Check battery polarity; replace with a new 9V battery. |
| Inaccurate readings | Incorrect grain scale selected; sample chamber not clean; device not calibrated | Ensure correct grain type is selected; clean sample chamber thoroughly; perform calibration if necessary. |
| Display shows error message | Sensor issue; extreme conditions | Refer to the specific error code in the full manual (if available); ensure operating within specified temperature/moisture ranges. |
