INSTALLATION

1. Remove the 2 phillips screws from behind the display (you don't
have to go inside the meter) holding the rectangular backplate to
the meter. Remove the backplate and set aside.

2. Cut or punch a hole in the panel where you want the meter to
go. The panel can be as thick as 0.25" (6.4mm) to as thin as

0.03" (0.8mm).

3. Insert the meter into the panel cutout.

4. From the rear of the panel, slide the backplate over the case
(smooth side out).

5. Install the 2 phillips screws to secure the meter in 1/8 DIN
mount. Center the meter in hole prior to tightening screws.

CALIBRATION

1. Apply the minimum current or voltage to the signal input.
Adjust the zero pot for the minimum display reading ±1 count.

2. Apply the maximum current or voltage to the signal input.
Adjust the span pot for the maximum display reading ±1 count.

3. Repeat steps 1 and 2 until ±1 count desired reading. Reinstall
the lens.
