NOTE
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 -
• Do not operate the instrument in the presence of ammable gas, explo­sive gas or vapor. This is extremely dangerous.
• Never apply more than 30V between any two terminals, or between terminal and ground.
Caution -
• The split case (top and bottom) is not to be removed, unless by qualied technicians.
• To clean the instrument, periodically wipe the case with a damp cloth and mild detergent, do not use any corrosive solvents.
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 [email protected].

1. Insert one end of the test lead to the ‘XMT’ output jack of the calibrator and connect the other end with the input terminal of the user’s instrument as shown in the following diagram:
2. The button-operation is the same as that as indicated in the Current Output section
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: [email protected].
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.
4. Put the battery cover back on and lock it in the indicated direction. Put the holster back on the calibrator.
