INTRODUCTION
Thank you for purchasing the Triminator Moisture Meter (TMM) Pin-Type LED Bar Graph Moisture
Meter. Please read this user’s manual carefully and thoroughly before using the meter.
The TMM is designed for applications in post-harvest cannabis processing. Examples include:
● Checking the moisture content of your flower before trimming or packaging
The meter bases its measurements on the relationship between the moisture content of a material
and its electrical conductivity. The wetter a material, the higher its conductivity.
The two replaceable steel pins at the top of the TMM serve as electrodes of a conductance meter
optimized for measuring moisture content. The meter displays measurements of the material’s %
moisture.
For super dense flower, the meter’s readings largely reflect surface moisture content because:
1. Moisture that is close to the surface has a greater effect on the reading than moisture deep
below it; and
2. The pins of the TMM are only 3/8 in. (10mm) long and cannot be driven deep into dense
material. For softer materials like soil, paper, or powders, readings are more likely to reflect
the average moisture level of the material between its surface and the penetration depth of
the pins (normally far less than 3/8 in.). The TMM’s front-panel bar graph of 10 LEDs
measures % moisture over two different ranges: 7 to 15% (LOW), and 16 to 35% (HIGH). A slide
switch on the back of the meter requires the user to choose the right range for the material
under test. The same switch functions as the power switch. Whenever the meter is powered
on, the bar graph momentarily indicates the remaining battery life. After powering on, the
meter’s calibration can be checked by inserting the test pins into holes in the pin protection
cover.
The TMM is powered by a 9V battery included in the blister pack.
