Before using the calibrator inspect the case. Do not use the calibrator
if it is damaged or the case (or part of the case) is removed. Look for
cracks or missing plastic.
During measurement, do not contact the naked wire, connector, unused
terminal or the circuit under test.
Inspect the test leads for damaged insulation or exposed metal. Replace
damaged test leads with identical model number or electrical
specifications before using the Meter.
When using the test leads, keep your fingers behind the finger guards.
Use the Meter only as specified in this operating manual, otherwise the protection
provided by the Meter may be impaired.
lNever apply more than 30V between any two terminals, or between any
terminal and earth ground.

Replace the battery as soon as the battery indicator appears. With a
low battery, the Meter might produce false readings that can lead to
electric shock and personal injury.
The internal circuit of the calibrator shall not be altered at will to avoid
damage of the calibrator and any accident
Do not use or store the calibrator in an environment of high temperature,
humidity, explosive, inflammable and strong magnetic field. The
performance of the Meter may deteriorate after dampened
Under the influence of Radiated, Radio-Frequency Electromagnetic Field
phenomenon, the captioned model may malfunction and can self-recover
after the test.
When servicing the Meter, use only the same model number or identical
electrical specifications replacement part.
Constantly check the battery as it may lead when it has been using for
some time, replace the battery as soon as leaking appears. A leaking
battery will damage the calibrator.
Take out the battery when not using for a long time.

1. Press the pushbutton to turn the Calibrator on.
2. Press OUTPUT to display OUTPUT if the Calibrator is at input mode which displays
INPUT.
3. Press to select the requested TC type or DC mV range.
4. Press or to increment or decrement a digit.
5. Press or to step up or down from 0 to 9. Hold down to scroll faster.
6. Insert the test leads to the OUPUT terminals as figure 3.
7. Connect the other end of the test leads to the TC measurement equipment or the
DC mV measurement equipment.
When connecting the calibrator to the auto ranging DC mV measurement equipment
or TC measurement equipment, it must lock the range.
