Setting up the 830 as a transmitter
Configure your 830 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 position 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 830
constantly measures the input from the process sensor and
regulates the current in the 4-20 mA loop.
Once the PIE 830 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.

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.
