INTRODUCTION
Your Circuit-Test DMR-1100 Digital Multimeter incorporates the latest technology to
provide you with a feature packed instrument. With it you can measure a wide range
of voltages, current and resistance in the lab, shop, car and home. This product has
been designed for the electrician, technician and hobbyist.
FEATURES
Continuity Buzzer - easily check for continuity.
Diode Check - test diodes and other semiconductors for open and short circuits.
Overload Protection - protects the meter from overvoltage and incorrect range
selection.
Auto-Polarity - indication on display that polarity is reversed.
WARNING
1.
Set the function switch correctly before making any measurements.
2.
Do not operate the unit unless the case is completely closed.
3.
Disconnect test leads from equipment before removing the battery.
4.
Never connect unit to AC or DC powered circuits when function switch is set to
Ω
,
diode check or continuity.
5.
To safeguard against electrical shock or damage to instrument, never connect to
more than 1000V DC or 750V AC between input jacks and ground.
6.
Always inspect the instrument, test leads and other accessories for damage prior to
use.
7.
Read this instruction manual carefully and completely before using.
SAFETY PRECAUTIONS
High voltage AC and DC circuits are dangerous. Always consider circuits to be energized.
Never assume any equipment is de-energized. Lack of caution or poor safety practices
can be very dangerous and/or lethal.
