1 Safety notes
Please read this manual carefully and completely before you use the device for the first time. The
device may only be used by qualified personnel and repaired by PCE Instruments personnel.
Damage or injuries caused by non-observance of the manual are excluded from our liability and
not covered by our warranty.
• The device must only be used as described in this instruction manual. If used otherwise,
this can cause dangerous situations for the user and damage to the meter.
• The instrument may only be used if the environmental conditions (temperature, relative
humidity, …) are within the ranges stated in the technical specifications. Do not expose
the device to extreme temperatures, direct sunlight, extreme humidity or moisture.
• Do not use the meter during thunderstorms.
• Do not expose the device to shocks or strong vibrations. Dropping it can damage the
electronic parts or the case.
• The case should only be opened by qualified PCE Instruments personnel.
• Never use the instrument when your hands are wet. Keep the meter dry.
• You must not make any technical changes to the device.
• The appliance should only be cleaned with a damp cloth. Do not use chemicals,
cleaning solvents or detergents.
• The device must only be used with accessories from PCE Instruments or equivalent.
• Before each use, inspect the case for visible damage. If any damage is visible on the
meter or its test leads, do not use the device.
• Do not use the meter if it operates incorrectly. Protection may be compromised.
• Do not operate meter while Low Battery warning is on. Replace batteries immediately.
• Use only new batteries of the recommended size and type. Remove old or weak
batteries to avoid leakage and damage to the meter.
• If the meter is not used for a longer period of time, remove the batteries.
• Do not use the instrument in explosive atmospheres or near explosive vapours, dust or
gases.
• The measurement range as stated in the specifications must not be exceeded under
any circumstances.
• Ensure that the test leads are fully seated in the input jacks and keep your fingers away
from the metal probe tips when taking measurements.
• Before changing functions using the selector switch, always disconnect the test leads
from the circuit under test.
• Use only UL listed test leads with the proper safety category rating.
• Comply with all applicable safety codes. Use approved personal protective equipment
when working near live electrical circuits-particularly when there is arc-flash hazard.
• Use caution on live circuits. Voltages above 30 V AC RMS, 42 V AC peak, or 60 V DC
pose a shock hazard.
• Verify functionality before using meter by measuring a known live voltage.
• Do not apply voltage or current that exceeds the meter’s maximum rated input limits.
• Non-observance of the safety notes can cause damage to the device and injuries to
the user.

Category rating
Brief description
Typical applications
Cat II
Single phase receptacles
and connected loads
• Household appliances,
power tools
• Outlets more than 30 ft
(10 m) from a Cat III source
• Outlets more than 60 ft
(20 m) from a Cat IV source
Cat III
Three phase circuits and
single phase lighting circuits
in commercial buildings
• Equipment in fixed
installations such as
3-phase motors, switchgear
and distribution panels
• Lighting circuits in
commercial buildings
• Feeder lines in industrial
plants
• Any device or branch circuit
that is close to a Cat III
source
The measurement category (CAT) rating and voltage rating is determined by a combination of the
meter, test probes and any accessories connected to the meter and test probes. The combination
rating is the LOWEST of any individual component.
WARNING: Operation is limited to CAT II applications when the insulated tips are removed from
one or both test probes. Refer to the input limits section in this manual for maximum voltage
ratings.

5 Measuring functions
5.1 AC/DC voltage measurements
WARNING: Observe all safety precautions when working on live voltages.
1. Set the rotatory function switch to the V position.
2. To select AC or DC voltage, press the MODE-button until the
AC “~” or DC “ ”symbol appears on the LCD.
3. Insert the black test lead into the COM input jack and the red
test lead into the V input jack.
4. Touch the test lead probes to the circuit under test. If
measuring DC voltage, touch the red test lead to the positive
side of the circuit and the black test lead to the negative side
of the circuit.
5. Read the voltage on the display.
5.2 Low Z AC/DC voltage measurements
WARNING: Observe all safety precautions when working on live voltages. Do not connect to
circuits that exceed 300 V AC RMS or 300 V DC when the meter is set to Low Z.
Low Z is used to check for “ghost” voltage. Ghost voltages are present when non-powered wires
are in close proximity to powered wires. Capacitive coupling makes it appear that non-powered
wires are connected to a real source of voltage. The Low Z setting places a load on the circuit,
which greatly reduces the voltage reading when connected to ghost voltage.
1. Set the rotary function switch to the Low Z position.
2. To select AC or DC voltage, press the MODE button until the
AC “~” or DC “ ” symbol appears on the LCD.
3. Insert the black test lead into the COM input jack and the red
test lead into the V input jack.
4. Touch the test leads to the circuit under test. If measuring DC
voltage, touch the red test lead to the positive side of the
circuit and the black test lead to the negative side of the
circuit.
5. Read the voltage on the LCD.
