Dwyer Instruments MM10 Series Operating Instructions

SERIES MM10 DIGITAL MULTIMETER

SAFETY INFORMATION

The following safety information must be observed to insure
maximum personal safety during the operation of this meter.
Do not use the meter if the meter or test leads look damaged, or
if you suspect that the meter is not operating properly.
Never ground yourself when taking electrical measurements. Do
not touch exposed metal pipes, outlets, fixtures, etc., which might
be a ground potential. Keep your body isolated from ground by
using dry clothing, rubber shoes, rubber mats, or any approved
insulating material.
Turn off power to the circuit under test before cutting,
unsoldering, or breaking the circuit. Small amounts of current
can be dangerous.
Use caution when working above DC 60V or AC 30Vrms. Such
voltages pose a shock hazard.
When using the probes, keep your fingers behind the finger
guards on the probes.
Measuring voltage which exceeds the limits of the multimeter
may damage the meter and expose the operator to a shock
hazard. Always recognize the meter voltage limits as stated on
the front of the meter.
