Introduction

The HD110C Heavy-Duty Digital Multimeter is a 3-1/2 digit, manual ranging, ac-coupled average

measuring rms reading display instrument that measures: voltage, current, resistance, continuity, and

diode junctions. Menu selection allows Data Hold and ac or dc voltage and current selection.

Warnings and Precautions

This instrument is EN61010-1 certiﬁed for Cat IV, 1000 V ac/1500 V dc and lower installations.

Based on EN61010-1 transient requirements, this product should only be used in installations

where transients do not exceed 12,000 volts (a 1.2 µS/50 µS pulse).

• All inputs are protected against continuous overload conditions up to the limits of

each function's stated input protection (see speciﬁcations). Never exceed these limits or the

ratings marked on the instrument itself.

• Exercise extreme caution when: measuring voltag e >20 V, current >10 mA, ac power

line with inductive loads, ac power line during electrical storms. High voltages can be lethal

and high voltage transients may occur at any time.

• Operator injury or damage to the multimeter may occur during current measurements

if the fuse blows in a circuit with open circuit voltage exceeding 1000 V ac/1500 V dc.

• Always inspect your DMM, test leads and accessories for signs of damage or

abnormality before use. If an abnormal condition exists (broken or damaged test leads,

cracked case, display not reading, etc.), do not use. The internal fuse cover is integral to the

EN61010-1 Cat IV safety rating and must be in place to avoid potential shock hazards

• When testing for voltage or current, make sure these ranges function correctly. Take a

reading of a known voltage or current ﬁrst.

• Never ground yourself when taking measurements. Do not touch exposed metal pipes,

outlets, ﬁxtures, etc., which might be at ground potential. Keep your body isolated from

ground and never touch exposed wiring, connections, test probe tips, or any live circuit

conductors. Do not use the Flex-Strap to attach the meter to your body.

• Always measure current in series with the load – NEVER connect the multimeter
