Output signal is set at 30% (8.8
mA/2.2 V). A “#” character appears
on right side of display to remind
you that transmitter is in its output
mode.
7
Check that receiving device indication is
at its 30% point. If applicable, check that
milliammeter reading is 8.8 mA or
voltmeter reading is 2.2 V across 250
ohm resistor.
If indication is inaccurate, check
calibration of receiving device.
8
Repeat Steps 5 and 6 to check
indications at these output percentages.
If output is … Then meter
reads…
0% 4.0mA/1.0V
25% 8.0mA/2V
50% 12.0mA/3V
60% 13.6mA/3.4V
80% 16.8mA/4.2V
100% 20.0mA/5.0V
Use transmitter output as a
calibration input source for
instruments in loop.
