The memory feature provides 5 user settable source values for stepped calibration outputs. The
feature is available for Voltage, mA and % in the SOURCE mode. The memory values are stored in
nonvolatile memory and are not erased when power is turned off.
Sourcing from the stored memory values:
1. Select the Source mode
2. Press the MEM button. The M1 icon (memory location 1) will appear in the display and the
value stored in that location will be displayed and sourced.
3. Repeated pressing of the MEM button will step through the 5 memory locations.
NOTE: The SOURCE icon will blink when the output value has not reached a stable level.
The common cause for the SOURCE icon to remain blinking is that the load impedance is
too high in the current mode or too low in the voltage mode.
Storing values into memory:
1. Select and display a memory location (M1 to M5)
2. Press the buttons to adjust the display to the desired source value.
3. Press and hold the MEM button for > 2 seconds. The displayed value will be stored into the
displayed memory location.
Default memory values.

1. Turn the meter on and select the SOURCE mode.
2. Press and hold the POWER button for >4 seconds.
