WARNING
1.
Always start with the power off. Set the
range 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 or fuse.
4.
Never connect unit to AC or DC powered
circuits when the range switch is set to
resistance, diode check or continuity ranges.
5.
To safeguard against electrical shock or
damage to instrument, never connect to
more than 600V DC or 600V AC between
input jacks and ground when measuring
low energy circuits or 250VAC / 250VDC
when measuring high energy circuits.
6.
When using the test probes always keep
your fingers behind the finger guards on the
probes. Never touch the exposed probe tip.
7.
Always inspect the instrument, test leads
and other accessories for damage prior to
use.
8.
Disconnect the live / positive test lead prior
before disconnecting the common / negative
test lead.
9.
Read this instruction manual carefully and
completely before using.

SAFETY PRECAUTIONS
This meter is not recommended for high voltage
industrial use; for example, do not use for meas-
urements on 440VAC or 600VAC industrial
power mains. The unit is intended for use with
low energy circuits to 600VDC / 600VAC or high
energy circuits to 250VAC / 250VDC only.
High voltage AC and DC circuits are dangerous.
Use caution when working above 60VDC or
30VAC rms as these voltages pose a shock
hazard. Always consider circuits to be ener-
gized. Never assume any equipment is
de-energized. Lack of caution or poor safety
practices can be very dangerous and/or lethal.
SPECIAL FUNCTION
Max Data Hold - When PEAK-H is pressed, the
last reading is held on the display.
