For calibration, a calibrated current source and a screwdriver are required.

To access the input terminals, remove the enclosure cover and the display PCB. 

1.

Loosen the four screws on the enclosure cover and remove the cover.

2.

Completely loosen the left screw that holds the display PCB to the enclosure and 

loosen the right screw about four turns so the display PCB remains attached to the 
enclosure.

3.

Rotate the display PCB 90° to gain access to the input signal PCB.

4.

Next, connect a calibrated current source as shown in 

The decimal point jumper array is located in the lower right corner of the display PCB 
next to the display. It is labeled DP1, DP2, DP3. 

Place a jumper over both pins of DP1 for a display of 199.9, DP2 for 19.99, or DP3 for 1.999.

LO and HI calibration controls are located to the left of the display (see 

 on page 6). 

1.

Apply a signal equal to 4 mA and adjust the LO control to display the desired reading.

2.

Apply a signal between 16 and 20 mA and adjust the HI control to display the desired 

reading.

3.

Complete the calibration procedure by making any minor adjustments to the LO and 

HI controls.

To install the meter, remove the display PCB from its enclosure and connect a ½" conduit 
fitting to the hole provided. Refer to
