Congratulations! Your new instrument has been crafted according to quality standards
and contains quality components and workmanship. It has been inspected for proper
operation of all of its functions and tested by qualified factory technicians according to
the long-established standards of AMPROBE.

1) SAFETY

This manual contains information and warnings that must be followed for operating the
instrument safely and maintaining the instrument in a safe operating condition. If the
instrument is used in a manner not specified by the manufacturer, the protection
provided by the instrument may be impaired.

This meter meets the requirements for double insulation to IEC61010-2-032(1994),
EN61010-2-032(1995), UL3111-2-032(1999): Category III 600 Volts ac and dc.

OVERVOLTAGE INSTALLATION CATEGORIES, PER IEC61010:

OVERVOLTAGE CATEGORY II: Equipment of OVERVOLTAGE CATEGORY II is
energy-consuming equipment to be supplied from the fixed installation.
Note – Examples include household, office, and laboratory appliances.

OVERVOLTAGE CATEGORY III: Equipment of OVERVOLTAGE CATEGORY III is
equipment in fixed installations.
Note – Examples include switches in the fixed installation and some equipment for
industrial use with permanent connection to the fixed installation.

OVERVOLTAGE CATEGORY IV: Equipment of OVERVOLTAGE CATEGORY IV is
for use at the origin of the installation. Note – Examples include electricity meters and
primary over-current protection equipment.

TERMS IN THIS MANUAL

WARNING: Identifies conditions and actions that could result in serious injury or

even death to the user.

CAUTION: Identifies conditions and actions that could cause damage or

malfunction in the instrument.

WARNING:
To reduce the risk of fire or electric shock, do not expose this product to rain or
moisture. The meter is intended only for indoor use.

To avoid electrical shock hazard, observe the proper safety precautions when working
with voltages above 60 VDC or 30 VAC rms. These voltage levels pose a potential
shock hazard to the user.

Inspect test leads, connectors, and probes for damaged insulation or exposed metal
before using the instrument. If any defects are found, replace them immediately.

Do not touch test lead tips or the circuit being tested while power is applied to the
circuit being measured. To avoid accidental short circuit of bare (un-insulated)
hazardous live conductors or bus bars, switch them off before insertion and removal of
the current clamp jaws. Contact with the conductor could result in electric shock.

Keep your hands/fingers behind the hand/finger barriers that indicate the limits of safe
access of the meter and the test leads during measurement.

CAUTION:
Disconnect the test leads from the test points before changing meter functions.

DC Voltage, AC Voltage, Hz Frequency functions

Inputs are made through the test lead terminals. Move the slide-switch to the “V”
position. The unit defaults at DC voltage. Press SELECT button momentarily to select
AC voltage.

To activate the Hz Frequency function, press the Hz button momentarily.

Note: 400.0mV range is designed with 1000MΩ high input impedance for least current
drain in measuring small signals, and can cope better with most commercially available
voltage output transducers/adapters. The non-zero display reading is normal when the
meter inputs are open circuit, which will not affect actual measurement accuracy. The
