Operating Instructions
Setting up the 830PM as a transmitter
Configure your 830PM to the same Span (URV) and Zero (LRV) by storing Span
& Zero setting with the
q
EZ-CHECK switch.
1) Store your SPAN input by moving the
q
EZ-CHECK switch to the
MAX posi-
tion and turning the
e
EZ-Dial knob until the desired output value is on the
display. Press and hold the EZ-Dial knob until
STORED appears to store the
value. Release the EZ-Dial knob.
2) Store your ZERO input by moving the EZ-CHECK switch to the
MIN position
and turning the EZ-Dial knob until the desired output value is on the display.
Press and hold the EZ-Dial knob until
STORED appears to store the value.
Release the EZ-Dial knob.
3) Move the EZ-CHECK switch to the
READ position. The 830PM constantly
measures the input from the process sensor and regulates the current in the
4-20 mA loop.
Once the 830PM is setup and connected to the process sensor and the 4-20 mA
loop it acts just like a calibrated isolated transmitter and will display the input signal
from the sensor and the regulated 4-20 mA output signal. XMTR is shown on the
display along with L, N or S for Linear, Nonlinear or Square Root respectively.

830PM with LOOPSCOPE
For full loop diagnostics turn on LOOPSCOPE which indicates the current,
SUPPLY (voltage) and LOAD (resistance) of the loop. It also indicates errors by
flashing the LED and writing diagnostic messages including
LOW LOOP VOLT,
HIGH LOOP VOLT and HIGH LOOP IMPED.
