Safety Information
To ensure safe usage, the following signs are used only as specied in this
instruction manual.
WARNING Indicates that the current operation does not comply with
correct instruction, therefore causing potential hazards to the user or
instrument. This also indicates how to avoid such hazards.
! CAUTION Indicates that the current operation does not comply with
correct instructions, therefore causing potential hazards to the instrument.
Also indicates how to avoid incorrect operation.
NOTE Serves as a sign to remind the user that they must understand
the correct operation before proceeding.
To prevent the user and the instrument from electric shock and other
hazards, it is necessary to follow the following regulations:
Warning - WARNING
• Do not operate the instrument in the presence of ammable gas, explo-
sive gas or vapor. This is extremely dangerous.
• Never apply more than 30V between any two terminals, or between
terminal and ground.
Caution - ! CAUTION
• The split case (top and bottom) is not to be removed, unless by
qualied technicians.
• To clean the instrument, periodically wipe the case with a damp
cloth and mild detergent, do not use any corrosive solvents.
Note - NOTE
• For optimal accuracy, allow the instrument to warm up for 5
minutes before operating.
•
If the automatic reference-junction temperature compensation of the
instrument deviates from its designed accuracy, on this or any other REED
product, contact REED Instruments at info@reedinstruments.com.

Automatic power-off
As a default the instrument will be set to automatically turn itself off after
10 minutes without any action. Follow the steps below to turn the Auto-
Power Off function off.
1. Be sure the meter is powered off.
2. Press both the POWER and mA%/V buttons simultaneously. The
display will indicate the symbol ‘AP-XX’.
3. Press the button to activate or deactivate the Auto-Power Off
function. ‘AP-OF’ indicates that there is no automatic power-off
function set, and ‘AP-ON’ indicates the automatic power-off func-
tion is activated.
4. Turn the meter off to save the setting.
Outputs
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.

5. Press the button to change the numerical value of the set
digits. Hold the button and the value will keep varying.
25% Step Current Output
1. Connect the test leads to the meter as stated in the Current
Output procedures.
2. When the OUTPUT/IN/SW button is pressed, will appear
in the display it indicating the calibrator is in an output state.
3. Press the 25%/RAMP button and will appear on the LCD.
4. Press the mA%/V button to select the set output to mA or %
5. Press the button to change the output in a value of 25%,
in which 0% indicates 4mA and 100% indicates 20mA.

Current Output Set for Zero Point & Full Scale
1. Connect the test leads to the meter as stated in the Current Out-
put procedures.
2. Press the OUTPUT/IN/SW button and will appear on the
display indicating that the calibrator is in an output state.
3. Press the 100%/START button and the symbols ‘0’ and ‘FS’ will
appear in the display.
4. Press the button to set to 100% (full scale) and the current out-
put will be 20mA. Press the button to be set to 0% (zero point)
and the current output will be 4mA.
5. Press the 100%/START button again to exit.
Auto-Ramp
1. Connect the test leads to the meter as stated in the Current
Output procedures.
2. Press the OUTPUT/IN/SW button and will appear on the
display indicating that the calibrator is in an output state.
3. Press the STEP/AUTO button and the symbols , ‘OFF’, ‘L’
and ‘4mA’ will appear on the display indicating that the calibrator
is entering RAMP mode.
4. Press the 25%/RAMP button again to change the type of the
output ramp from ‘L’, ‘H’, and ‘ ’. ‘L’ indicates a low speed ramp,
which is set to a cycle of 60 seconds. ‘H’ 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
LCD indicating that the output is deactivated. Press the 100%/
START button again to resume output at the set ramp from the
pause value. When the ‘OFF’ symbol appears, press any one of
the buttons to bring the output back to 0% and 4mA.
