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 1 seconds 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 seconds 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.
