Operating Instructions
Power ON/OFF
Press the POWER button to turn the instrument on. To turn the instrument
off, press and hold the POWER button.
Auto Power-off
As a default the instrument will automatically turn off after 15 minutes
of inactivity. Follow the steps below to Enable/Disable the Auto-Power
Off function.
1. Turn the meter off.
2. Press the POWER button (to display the full screen).
3. Quickly press and hold the RANG button when the instrument is in
the maintenance state as indicated by "1.8.8.888".
4. "AP-XX" will now appear on the display.
5. Press the button to toggle between "AP-ON" & "AP-OF". 'AP-OF'
indicates that the automatic power-off function is disabled, while
'AP-ON' indicates the automatic power-off function is enabled.
6. Press the 100%/START button to save the required setting.
7. Press and hold the POWER button to exit the maintenance state and
turn the instrument off.
Output Function
The output terminal of the instrument can produce DC voltages set by the
user or simulating resistance.
Caution: Do not apply any voltage to the output terminal during the
operation. If any improper voltage is applied to the output terminal, it
will cause damage to the internal circuits.

4. Press the mA%/V button to select the set output mA or mA%.
5. Press the buttons to change the output values at 100%, in
which 0% indicates 4mA and 100% indicates 20mA.
6. Press the mA 100% button to exit.
Auto-Ramp
1. Connect the test leads to the meter as stated in the Current
Output procedures.
2. Press the button and
OUTPUT
will appear on the display
indicating that the calibrator is in an output state.
3. Press the STEP/AUTO button and the symbols
OUTPUT
, "OFF",
" ", "S" and "4mA" will appear on the display indicating that the
calibrator is entering RAMP mode.
4. Press the 25%/RAMP button to change the type of the output ramp
from "S", "F", and " ". " S" indicates a low speed ramp, which
is set to a cycle of 60 seconds. " F" indicates a high speed ramp,
which is set to a cycle of 30 seconds. " " indicates auto-stair step
ramp, which pauses 5 seconds at each step.
5. Press the 100%/START button to start output on the selected
output ramp. "ON" will appear on the LCD indicating that the output
is activated. Press the 100%/START button again and the output will
pause on the current value. "OFF" will appear on the display
indicating that the output is deactivated. Press the 100%/START
button again to resume output at the set ramp from the pause value.
