The PIE Model 830PM is more than a multifunction calibrator. It is also a loop
detective that is able to diagnose common problems that other test equipment
just can’t find. Have a flooded junction box or unknown ground faults? Our Loop
Diagnostic technology will detect it. Or use the LoopScope to see at a glance all
the parameters - milliamps, voltage and resistance - in the loop.
Stop throwing away perfectly good transmitters only to find the problem is
somewhere else in the loop. Setup the PIE Model 830PM as an isolated universal
transmitter and turn on the Loop Diagnostics. The display will tell you EXACTLY
the sensor input, the current output and if there is any uncontrolled current in the
loop due to a ground fault, corrosion bridge or moisture. If the control system sees
no problem when the 830PM is acting as a transmitter THEN you can replace the
faulty transmitter. With RTDs the 830PM automatically detects which of the 2, 3 or
4 wires are connected and unbroken quickly alerting you to a sensor problem.
Diagnostic features are covered by
US Patent #7,248,058.

moving the EZ-CHECK™ switch to the “LO” position
or “HI” position. For fast three point checks select
the “SET” position. The 830PM will remember
the last “SET” value, even with the power off.
These values can easily be changed to suit the
calibration requirements. The values stored in the HI
and LO positions are also used for Auto Stepping.
READ: Slide the switch to the SET position. The
830PM will display the current input value. Slide the
switch to HI and the highest value measured since
turn-on or reset will be displayed; slide the switch to
LO and the lowest value measured since turn-on or
reset will be displayed.
wSOURCE/OFF/READ Switch

Operating Instructions
MODE - pressing the knob will cycle through OFF, LINEAR, NONLINEAR. When
setup to read pressure SQ ROOT replaces NONLINEAR.
LINEAR turns on the mA display and regulates the loop current linear with the
input signal. For thermocouples & RTDs this is linear relative to the temperature
between zero and span of the sensor input. This mimics the operation of a
digital temperature transmitter or other linearizing transmitters.
NONLINEAR (applies only to thermocouples and RTDs) turns on the mA
display and regulates the loop current linear with base units (millivolts or
ohms) of zero and span of the sensor input. This mimics the operation of an
analog temperature transmitter without linearizing.
SQ ROOT turns on the mA display and regulates the loop current with square
root extraction of zero and span of the pressure module input. This mimics the
operation of a differential pressure transmitter setup for square root extraction.
BURNOUT selects the failure mode of the calibrator when the input signal is lost or
beyond the input scale. Down sets the output to 1.0 mA and UP to 21.5 mA when
sensor failure is detected.
LOOPSCOPE turns on the Loop Diagnostic display which simultaneously
indicates the current, voltage and resistance of the loop. When enabled the
LOOPSCOPE also indicates errors by flashing the LED and writing diagnostic
messages on the display. Messages include LOW LOOP VOLT, HIGH LOOP
VOLT and HIGH LOOP IMPED.With LOOPSCOPE on the 830PM occasionally
performs a test on the loop. During this short test the loop mA signal will be
affected.

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.

250ΩHART resistor active in the loop.
Connect the output leads of the 830PM to the inputs of the device being
calibrated, making sure to check polarity. Red lead from jack (5) to the plus (+)
input and black lead from jack (6) to the minus (-) input. Open loops and signals
above the maximum scale are limited by protection circuitry with “ERROR” or
“OVER RANGE” flashed on the display and the red OVERLOAD LED lit.
Instantly output your SPAN and ZERO output settings by moving the EZ-CHECK
switch between HI and LO (defaults to 20 & 4 mA).You may also select any third
output setting (such as mid-range) using the SET position on the EZ-CHECK
switch. The output is adjusted in 0.001 mA (0.01%) increments by turning the
knob e. Press and turn the knob for faster dialing with 0.100 mA (1.00%)

Operating Instructions
Using Ground Leak Detection
mA OUT, % OUT (Percent of 4 to 20 mA)
Find current leaks in loops caused by ground faults, moisture or corrosion. The
830PM simultaneously supplies power to a 2 Wire Transmitter (or loop with a
transmitter) while displaying the 4 to 20 mA output and the amount of current
leaking in the loop.
1) Move the power switch w to READ then Double Click the EZ-DIAL knob to
get into the Menu. Turn the knob eto scroll through the settings and press the
knob to make your selection. Select mA for the FUNCTION and PWR MEAS
for the MODE. Choose either mA or %.
2) Turn the knob euntil the following menu appears.
3) Turn the knob eto scroll through the settings and press the knob to make
your selection. Turn on the LEAK DETECT.
4) Connect the red source lead from the mA (+) jack of the 830PM to the plus
(+) input of the device and the black source lead from the mA (-) to the minus
(-).
The 830PM supplies a nominal 24 volts DC at 24 mA to the 2 Wire Transmitter
or loop. The current passed by the transmitter will be accurately displayed by the
830PM along with an indication of leakage current at the top of the display. If
there is an uncontrolled loop, a transmitter with upscale burnout and bad or
missing sensor or a short the display shows "OVER RANGE”

Note: Many installed transmitters will normally
indicate 0.01 to 0.02 mA leakage without significant
control problem. Unstable readings may indicate
loose connections or the presence of moisture.
Typical Error Conditions
The 830PM is supplying the
loop voltage. There is a control
loop error. This may be a
transmitter (set for upscale
burnout) with a bad or missing
sensor, or a short in the loop.
The 830PM is supplying the loop
voltage. A calibrated transmitter is
limiting the loop current to 12.00
mA. An additional 0.28 mA is not
controlled by the transmitter and
is leaking somewhere in the loop.
