Description
The Greenlee IPM-100 Industrial Process Control Loop Calibrator is a hand-held testing device
intended to calibrate any standard 4 mA to 20 mA industrial process control loop.
It has the ability to:
• Check, measure, and calibrate all current signal instruments in a 4 mA to 20 mA DC loop.
• Provide a 0.00 mA to 24.0 mA source.
• Simulate a 2-wire transmitter.
• Simultaneously power and measure a 2-wire transmitter.
• Display either current (0 mA to 24 mA) or percent (–25% to 125%).

Introduction
The user can change the SET button to any other convenient set point (see Settings). In
addition, the control knob is speed-sensitive; turning it faster produces a faster change in the
output.
The normal industrial process control loop current range, or span, is 4 mA to 20 mA (0% to
100%). Intermediate points are as follows:
Settings
The IPM-100 has two selectable settings: Automatic Power-off and the current/percent
set point of the SET button.
To change Automatic Power-off setting:
1. Press and hold the SET button while turning the unit on.
2. After the firmware revision appears on the display, release the SET button. BAT and
ON indicate that Automatic Power-off is enabled.
3. Press the MODE button to change the Automatic Power-off function (ON or OFF).
4. Press the SET button to store your selection.
To change current/percent set point for SET button:
1. Use the control knob to set the output to the desired value.
2. Press the SET button to store the selected value.

Operation
Source
The Source Function relies on the batteries of the
IPM-100, and provides an output from 0.00 mA to
24.0 mA (–25 to 125%).
1. Disconnect one or both of the input wires
from the device to be calibrated.
2. Select SOURCE and press the MODE button
until SOURCE appears on the display.
3. Press the mA / % button to select current or
percent.
4. Connect the red lead to the positive (+) input
of the device; connect the black lead to the
negative (–) input of the device.
5. Adjust the output current by turning the
control knob, or by using the output
checkpoint buttons.
Read
The Read Function measures current from
0.00 mA to 24.0 mA (–25% to 125%).
1. Open the loop at any convenient point.
2. Select READ and press the MODE button until
READ appears on the display.
3. Press the mA / % button to select current or
percent.
4. Connect the red lead to the positive (+) side
of the circuit; connect the black lead to the
negative (–) side of the circuit.
5. Read the display.

2-Wire Simulator
The 2-Wire Simulator Function relies on an external power supply (3 VDC to 45 VDC), and
provides an output from 0.00 mA to 24.0 mA (–25% to 125%).
1. Disconnect the 2-wire transmitter from the loop.
2. Select 2-WIRE SIMULATOR and press the MODE button until 2-WIRE appears on the
display.
3. Press the mA / % button to select current or percent.
4. Connect the red lead to the positive (+) side of the circuit; connect the black lead to the
negative (–) side of the circuit.
5. Adjust the output current by turning the control knob, or by using the output checkpoint
buttons.
