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.

NOTE
• Power supply range: 5 to 25VDC
• During an output operation, use a external 24V DC power
supply in order to prolong battery life.
Calibrator Measurement
WARNING
• Never apply more than 30V between any two terminals, or between
any terminal and the ground. Any voltage more than 30V could result
in damage to the calibrator, as well as personal injury.
! CAUTION
• During operation, do not apply a voltage or current exceeding the
measuring range to the input terminal. This could cause damage to
the calibrator.
• During the operation, turn off the instrument before connecting the
calibrator. Connecting to the Calibrator without it being shut it down
may cause damage.

Calibration
It is recommended that you calibrate the unit once per year in order
to keep correct accuracies. Contact REED Instruments for assistance
regarding calibration, repairs, warranty, trouble-shooting, and more at:
Battery Replacement
When the appears on the LCD, the batteries need to be replaced.
Follow the instructions below to properly replace the batteries.
1. Turn the power off the meter and remove any test leads that may
be attached to the meter.
2. Remove the holster from the calibrator by releasing the lock in the
indicated direction.
3. Replace the old battery with a new 9V battery. Be sure to check
polarities. Do not mix old batteries with new batteries.
