Keypad Descriptions and Operation

POWER BUTTON and AUTO POWER OFF FEATURE

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.
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.
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 “APO” 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 1 second 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 1 second to zero the meter.

► ◄ ▼ and ▲ BUTTONS

The arrow buttons are used to set the output value in the SOURCE mode.

Select the SOURCE mode
Press the ► or ◄ button select a digit for adjustment. The blinking underline curser identifies the digit selected.
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.

Select the SOURCE mode
Press the SET button and the value stored in memory location 01 will be sourced. “MEM.01” appears in the display.
Each press of the SET button will step through the 5 memory locations.
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.

Select the SOURCE mode
Press and HOLD the STEP/MEM button. ”STEPS” (single cycle) and “STEPC” (continuous cycle) will alternately appear in the display. Release the button when the desired mode is
displayed.
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.
In the continuous mode the cycle will continue until manually stopped.
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:

To change the values in memory:

Select the SOURCE mode
Press the SET button to select the memory location to be changed.
Press the arrow buttons to adjust to the new value
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.

Turn the meter ON.
“MEASURE” will appear in the display.
Press the UNIT button to select mA or %
Press and HOLD the “MODE-I/O” button for 1 second if 24V loop power is required. “Lp.POWER” will appear in the display.
Connect the Calibration Cable to the meter.
Connect the Calibration Cable to the device or circuit under test.
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.

Turn the meter ON
Press the “I/O” button to select SOURCE.
Use the UNIT button to select % or mA.
Connect the Calibration Cable to the meter
Connect the Calibration Cable to the device or circuit under test
Use the arrow buttons to set the desired output value in the lower display. The upper display indicates the actual current value being sourced. If the upper display does not match
the set value, either the batteries need to be replaced or the load impedance is beyond the specified range.

Tilt Stand / Hanger

The rear stand is provides two methods for convenience in viewing.

Pull the bottom portion of the stand out to place the unit on a flat surface for viewing.
Pull the bottom and top portions of the stand out, and then rotate the stand to allow the unit to be hung.
