Keypad Descriptions and Operation
POWER BUTTON and AUTO POWER OFF FEATURE
1. Use the POWER button to turn the unit ON or OFF. When the unit is powered up, a short
self-test will ensue after which the display will stabilize.
2. When the battery symbol flashes on the display, replace the battery as soon as possible.
Low battery power may cause inaccurate readings and erratic meter operation.
3. This instrument is equipped with Auto Power OFF which turns the meter off after 10 minutes
of inactivity. To override this feature; press and hold the POWER button until the display
icon “ATP” turns off.
UNIT BUTTON
Press the UNIT button to select mA or %units.
I/O BUTTON
Momentarily press the I/O button to select either SOURCE (output) or MEASURE (input).
MODE BUTTON (Loop Power)
In the MEASURE mode, Press and Hold the MODE (I/O) button for 1seconds to turn loop power on
or off.
(Backlight) BUTTON
Momentarily press the Backlight button to turn the backlight on or off.
ZERO ( ) BUTTON
In the MEASURE or SOURCE mode, Press and Hold the ZERO ( ) button for 1seconds to zero
the meter.
► ◄ ▼and ▲BUTTONS
The arrow buttons are used to set the output value in the SOURCE mode.
1. Select the SOURCE mode
2. Press the ►or ◄button select a digit for adjustment. The blinking underline curser
identifies the digit selected.
3. Press the ▼or ▲button to adjust the value of the digit. Press and Hold the ▼or ▲button to
rapidly adjust the value.

SET BUTTON
The SET button is used to manually step through the 5 stored output values.
1. Select the SOURCE mode
2. Press the SET button and the value stored in memory location 01 will be sourced. “MEM.01”
appears in the display.
3. Each press of the SET button will step through the 5 memory locations.
4. The arrow buttons can be used to adjust the value in each memory location.
STEP/MEM BUTTON
The STEP/MEM button is used to automatically step through the 5 stored output values. The meter
can be set for a single cycle of the stored values or a continuous cycle.
1. Select the SOURCE mode
2. Press and HOLD the STEP/MEM button. ”STEPSS” (single cycle) and “STEPSC”
(continuous cycle) will alternately appear in the display. Release the button when the
desired mode is displayed.
3. In single cycle mode the meter will source the current displayed in MEM01 for 5 seconds.
The meter will then advance to MEM02 for 5 seconds. This will continue through MEM05
and then step down through the memory locations. The cycle will end when MEM01 has
been reached.
4. In the continuous mode the cycle will continue until manually stopped.
5. Momentarily press the STEP/MEM button to stop the cycle. “END” will briefly appear in the
display.
STORING VALUES INTO MEMORY
The default values stored in the memory locations are:
Memory
Location mA %
M1 4.00mA 0.0%
M2 8.00mA 25%
M3 12.00mA 50%
M4 16.00mA 75%
M5 20.00mA 100%
To change the values in memory:
1. Select the SOURCE mode
2. Press the SET button to select the memory location to be changed.
3. Press the arrow buttons to adjust to the new value
4. Momentarily press the MEM button to store the value. The memory location icon will blink
while the value is being stored.

Modes of Operation
MEASURE (Input) Mode of Operation
In this mode, the unit will measure up to 50mADC.
1. Turn the meter ON.
2. “MEASURE” will appear in the display.
3. Press the UNIT button to select mA or %
4. Press and HOLD the “MODE-I/O” button for 2 seconds if 24V loop power is required.
“Lp.POWER” will appear in the display.
5. Connect the Calibration Cable to the meter.
6. Connect the Calibration Cable to the device or circuit under test.
7. Read the measurement on the LCD display.
SOURCE (Output) Mode of Operation
In this mode, the unit can source current up to 24mADC at 1000 ohms. The current can be output
either manually or stepped from memory as described earlier.
1. Turn the meter ON
2. Press the “I/O” button to select SOURCE.
3. Use the UNIT button to select %or mA.
4. Connect the Calibration Cable to the meter
