1000-PROC Process
The 1000-PROC Process meter accepts either voltage or current
inputs (0 to 5, 1 to 5 or 0 to 10 Vdc) or (0 to 20mA, 4 to 20mA).
Note: The unit is shipped from the factory calibrated to display 0
to 1000 counts with a 4 to 20mA input signal.
If the unit is to be used for 0 to 20mA, 0 or 1 to 5Vdc or 0 to
10Vdc it must be recalibrated according to the instructions in
Chapter 5. Voltage or current inputs are selected simply by wiring
the inputs to the proper rear terminals by installing removable
jumpers located on the main board and adjusting the scaling
potentiometer located behind the front panel lens (see figure page
2). To place the decimal point in the desired location, place the
jumper provided below the main display. Use the table on the
following page to scale the meter.
Note: The table on the following page is based on 0 display counts
with 0 input. Offsets above zero (maximum 500 counts) will be
added to the full-scale range. It may be necessary to change
jumper settings to achieve the desired display range.
Range Table
Sensor Input Accuracy Resolution
0 to 20/4 to 20mA 0.5% 1count of 1999 counts
0 to 5/1 to 5Vdc 0.5%
0 to 10 Vdc 0.5%
Example: Scale the meter to display 200 counts with 4mA input
and 1500 counts with 20mA input.
1. Install a single jumper jack on position 6. Input 20.0 mA and
adjust the SCALE pot to 1500 counts.
2. Input 4.0 mA and adjust the ZERO pot to 200.
