2.- ADJUST AND CALIBRATION PROCEDURE
1.- Open the housing to access the instrument internal circuits
2.- Select apropriate jumpers on boards ME, MP and MS
3.- Connect signal generator to signal input terminals
Connect multimeter to signal output terminals
4.- Power up the instrument as indicated on the label
5.- Generate the signal level low
Operate potentiometer P1 on ME until indication shows desired signal output low level
6.- Generate the signal level high
Operate potentiometer P2 on ME until indication shows desired signal output low level
7.- Repeat steps 6 to 9 in order to correct deviations and check adjust
