APPENDIX
IMPORTANT
This page is only for models with date code prior to 0816.
Pre 0816 Date Code Configuration
Select the proper output, mode, and pressure range using the switches and jumpers:
1. Select output using the output switch:
a. Current: mA (then skip to step 3), or
b. Voltage: Volt.
2. Select 0-10 Vdc or 0-5 Vdc using jumper J4.
3. Select bi- or uni-directional mode using jumper J5.
NOTE: Setting for 0 to 1 in. w.c. and bi-directional will give output from -1.0 to 1.0 in. w.c.
4. Select appropriate full-scale pressure range using the slide switch.
NOTE: Note that either the 1 in. w.c. or 10 in. w.c. scale is marked. This is the available scale for that given
model. When the range is changed, the LCD models momentarily indicate selected range.
