1000-PROC Process Meter

The 1000-PROC can be custom scaled to display a full-scale

reading from 200 to 1999 counts by installing removable jumpers

located on the main board and adjusting the scaling potentiometer

located behind the front panel lens.

4-20mA

Equipment Required:

1. Precision DC current source with a resolution of 0.1ma DC

and an accuracy of 0.1%.

2. Interconnecting copper wire from the DC current source to the

indicator.

3. Trimmer adjusting tool.

STEP 1. Disconnect power from the unit and remove the front

panel lens.

STEP 2. Connect the DC current source to terminal 1 (+) and

terminal 2 (-) located on the rear of the unit. Reconnect power and

turn the unit on. Allow for a 5-minute warm-up.

STEP 3. Input 4.0mA from the DC current source and adjust the

ZERO pot for a display reading of 0.0 ± 1 count.

STEP 4. Input 20.0 mA from the DC current voltage source and

adjust the SPAN pot for a reading of 100.0±1 count.

STEP 5. Repeat steps 3 and 4 until no further adjustment is

needed.
