Introduction
The Digi-Sense Insulation Tester (Model 20250-60) is
versatile and easy to use. The instrument is a must-have
on your electrical tool belt. It safely measures insulation
resistance of electrical devices such as cables or motor
coils up to 4000 M
Ω
, as well as providing a means of
measuring AC/DC voltages and circuit continuity. Careful
use of this meter will provide years of reliable service.
Safety Precautions
•
Read the following safety information carefully before
attempting to operate or service the meter.
•
To avoid damages to the instrument do not apply the
signals which exceed the maximum limits shown in the
technical specifications tables.
•
Do not use the meter or test leads if they look damaged.
Use extreme caution when working around bare
conductors or bus bars.
•
Accidental contact with the conductor could result in
electric shock.
•
Use the meter only as specified in this manual; otherwise,
the protection provided by the meter may be impaired.
•
Read the operating instructions before use and follow
all safety Information.
•
Caution when working with voltages above 60 VDC or
30 VAC RMS. Such voltages pose a shock hazard.
•
Before taking resistance measurements or testing
acoustic continuity, disconnect circuit from main power
supply and all loads from the circuit.
