Performance Test for mini-Ligno Series:

Step 1: When the on-off switch is depressed by hand without touching the pins, the lowest moisture value is indicated: 6% for mini-Ligno ED on species setting #3.

Step 2: When the on-off switch is depressed by hand and both pins are touched with two fingers at the same time at least 12% should be indicated.

Step 3 optional: The external test block TP checks calibration and operation of all Lignomat pin meters, including cable and electrode. All Lignomat meters internally, automatically check and adjust the calibration. Therefore manual recalibration is not necessary.

If steps 1, 2 or 3 fail either the battery needs to be replaced or the mini-Ligno is defective.
