3 Safety Information
For the correct and safe use of the instrument, be sure to follow the cautionary notes stated in this manual
whenever handling the instrument. The Company shall not be held liable for any damage resulting from use of
the instrument in a manner other than prescribed in the cautionary notes.
A Warning identifies conditions and actions that pose hazards to the user; a Caution identifies conditions
and actions that may damage the meter or the equipment under test.
Refer to Table 1 for the explanation of the international electric symbols adopted by the calibrator or the user’s
manual.

WARNING
INFORMATION
Warning
To avoid possible electric shock or personal injury:
zDo not apply more than the rated voltage, as marked on the calibrator, between terminals or between any
terminal and earth ground;
zBefore use, verify the meter’s operation by measuring a known voltage;
zFollow all equipment safety procedures;
zDo not connect the probe of the testing lead with any live power when the other end has been inserted into
the current jack;

5
zDo not use the meter if it is damaged. Before using the meter, inspect the case. Look for cracks or missing
plastic .Pay particular attention to the insulation surrounding the connectors;
zSelect the proper function and range for the measurement;
zMake sure the battery door is closed and latched before operating the meter;
zRemove test leads from the meter before opening the battery door;
zInspect the test leads for damaged insulation or exposed metal. Check test lead continuity. Replace
damaged test leads before using the meter;
zWhen using the probes, keep fingers behind the finger guards on the probes;
zConnect the common test lead before connecting the live test lead. When disconnecting test leads,
disconnect the live test lead first;
zDo not use the meter if it operates abnormally. Protection may be impaired. When in doubt, have the
meter inspect;
zDo not operate this instrument in areas where inflammable or explosive gases or vapor exists. It is
extremely hazardous to use the instrument under such environments;
zDo not operate the meter around explosive gas, vapor, or dust;
zWhen use the pressure module, do make sure the process pressure line is shut off and depressurized
before connecting or disconnecting the pressure module;

6
zUse only type 4 AAA batteries, properly installed in the meter case, to power the meter;
zDo disconnect the testing lead before shifting to different source or measurement functions;
zWhen servicing the meter, use only specified replacement parts.
zTo avoid false reading, which could lead to possible electric shock or personal injury, replace the batteries
as soon as the low battery indicator ( ) appears.
z
Caution
To avoid possible damage to meter or to equipment under test:
zDisconnect the power and discharge all high-voltage capacitors before testing continuity.
zUse the proper jacks, functions, and ranges for the measurement or source operation.
