INTRODUCTION
This tester can measure grounding resistance and AC voltage up to 200V. 2mA current test
signal permits grounding resistance tester without tripping current breakers in the circuit
under fest. lt can be used in the grounding resistance measurements of Power System,
electrical device, lightning protection device, etc. lt is easy to use and has a high precision.
SAFETY INFORMATION
This fester has been designed according to IEC-61010 concerning electronic measuring
instruments with a measurement category (CAT III 200V).
Warning
To avoid possible electric shock or personal injury, follow these guidelines:
•
Do not use the tester if it is damaged. Before you use the fester, inspect the Case. Pay
particular attention to the insulation surrounding the connectors.
•
Inspect the test leads for damaged insulation or exposed metal. Check the fest leads
or continuity. Replace damaged fest leads before you use the tester.
•
Do not use the tester if it operates abnormally. Protection
may be impaired. When in doubt, have the tester serviced.
•
Do not operate the tester around explosive gas, vapor, or dust.
•
Do not apply more than the rated voltage, as marked on the fester, between terminals
or between any terminal and earth ground.
•
Before use, verify the testers operation by measuring a known voltage.
•
When servicing the fester, use only specified replacement parts.
•
Use caution when working above 30V ac RMS, 42V peak, or 60V dc. Such voltages
pose a shock hazard.
•
When using the probes, keep your fingers behind the finger guards on the probes.
When using the Clips, don't touch metal or conductor with finger or skin for safely.
•
Remove the fest leads from the tester before you open the battery door or the case.
•
Do not operate the tester with the battery door or portions of the case removed or
loosened.
•
To avoid false readings, which could lead to possible electric shock or personal
injury, replace the batteries as soon as the low battery indicator appears or when the
display is blank.
•
Don't use hand or skin to touch any earth electrode which may be live or high power.
Don't use hand or skin to touch any auxiliary earth bar while testing.
Remaining endangerment:
When an input terminal is connected to dangerous live potential it is to be noted that
this potential at all other terminals can occur!
•
If the tester is used in a manner not specified by the manufacturer, the protection
provided by the fester will be impaired.
•
CAT III is for measurements performed in the building Installation, examples in
measurements in distribution boards, circuitbreakers, wiring, including gables, bus-
bare, junction boxes, switches, socket outlets in the fixed Installation, and equipment
for industrial use and some other equipment, for example, stationary motors with
permanent connection to the fixed installation. Don't use the equipment tor
measurement within Measurement Categories IV.
Caution
To avoid possible damage to the tester or to the equipment under fest, follow these
guidelines:
•
Use the proper terminals, function, and range for your measurements.
•
Before turning on the tester for measuring, make sure that the plugs of the fest leads
have been well inserted to the specified sockets.
•
Before turning the function/range switch to change functions, disconnect test leads
from the circuit (or object) under fest.
•
Remove fest leads from the tester before opening the battery door or case.
•
Don't use the tester in damp weather.
