2. INTRODUCTION
Specially designed for hybrid vehicles and conforms to EN61010 CAT III (1000V) and CAT IV (600V). Unlike other multimeters this
unit has an insulation test function that allows testing of the insulation of the high voltage cables and motor generator units found on
hybrid vehicles. Can be used as a standalone device or linked wirelessly with a USB interface to a PC or laptop enabling results to be
graphed, saved or printed. Supplied with high voltage probes, thermocouple soft storage bag and wireless USB cable. The unit also has
theusualfunctionsexpectedonahighqualitymultimeterincludingtrueRMS(Root-Mean-Square)andIP67waterproofrating.

Safety Symbols This symbol adjacent to another symbol, terminal
or operating device indicates that the operator
must refer to an explanation in the Operating
Instructions to avoid personal injury or damage to
the meter.
This WARNING symbol indicates a potentially
hazardous situation, which if not avoided, could
result in death or serious injury.
This CAUTION symbol indicates a potentially
hazardous situation, which if not avoided, may
result in damage to the product.
This symbol advises the user that the terminal(s)
so marked must not be connected to a circuit point
at which the voltage with respect to earth ground
exceeds (in this case) 1000 VAC or VDC.
This symbol adjacent to one or more terminals
identifies them as being associated with ranges
that may, in normal use, be subjected to
particularly hazardous voltages. For maximum
safety, the meter and its test leads should not be
handled when these terminals are energized.
This symbol indicates that a device is protected
throughout by double insulation or reinforced
insulation.

ELECTRICAL SAFETY PRECAUTIONS
This meter has been designed for safe use, but must be operated with
caution. The rules listed below must be carefully followed for safe
operation.
1. NEVER apply voltage or current to the meter that exceeds the
specified maximum:
Input Protection Limits
Function Maximum Input
V DC or V AC 1000VDC/AC rms
mA AC/DC 500mA 1000V fast acting fuse
AAC/DC
10A 1000V fast acting fuse (20A
for 30 seconds max every 15
minutes)
Frequency, Resistance,
Capacitance, Duty Cycle,
Diode Test, Continuity
1000VDC/AC rms
Temperature 1000VDC/AC rms
Surge Protection: 8kV peak per IEC 61010
2. USE EXTREME CAUTION when working with high voltages.
3. DO NOT measure voltage if the voltage on the "COM" input jack
exceeds 1000V above earth ground.
4. NEVER connect the meter leads across a voltage source while
the function switch is in the current, resistance, or diode mode.
Doing so can damage the meter.
5. ALWAYS discharge filter capacitors in power supplies and
disconnect the power when making resistance or diode tests.
6. ALWAYS turn off the power and disconnect the test leads before
opening the covers to replace the fuse or batteries.

7. NEVER operate the meter unless the back cover and the battery
and fuse covers are in place and fastened securely.
If the equipment is used in a manner not specified by the
manufacturer, the protection provided by the equipment may be
impaired.

Operating Instructions
WARNING: Risk of electrocution. High-voltage circuits, both AC and
DC, are very dangerous and should be measured with great care.
1.ALWAYS turn the function switch to the OFF position when the
meter is not in use.
2.If “OL” appears in the display during a measurement, the value
exceeds the range you have selected. Change to a higher range.
DC VOLTAGE MEASUREMENTS
CAUTION: Do not measure DC voltages if a motor on the circuit
is being switched ON or OFF. Large voltage surges may occur
that can damage the meter.
1. Set the function switch to the green VDC
position.
2. Insert the black test lead banana plug into the
negative COM jack.
Insert the red test lead banana plug into the
positive Vjack.
3. Touch the black test probe tip to the negative
side of the circuit.
Touch the red test probe tip to the positive
side of the circuit.
4. Read the voltage in the display.

AC VOLTAGE (FREQUENCY, DUTY CYCLE) MEASUREMENTS
WARNING: Risk of Electrocution. The probe tips may not be long
enough to contact the live parts inside some 240V outlets for
appliances because the contacts are recessed deep in the outlets.
As a result, the reading may show 0 volts when the outlet actually
has voltage on it. Make sure the probe tips are touching the metal
contacts inside the outlet before assuming that no voltage is
present.
CAUTION: Do not measure AC voltages if a motor on the circuit
is being switched ON or OFF. Large voltage surges may occur
that can damage the meter.
1. Set the function switch to the green
VAC/Hz/% position.
2. Insert the black test lead banana plug
into the negative COM jack.
Insert red test lead banana plug into the
positive Vjack.
3. Touch the black test probe tip to the
neutral side of the circuit.
Touch the red test probe tip to the “hot”
side of the circuit.
4. Read the voltage in the main display and
the frequency in the right auxiliary
display
5. Press and hold the MODE button 2 second to indicate “Hz”.
6. Read the frequency in the main display.
7. Press the MODE button to indicate “%”.
8. Read the % of duty cycle in the main display.
9. Press EXIT for 2 seconds into the function of AC+DC. Test DC
and AC True Rms.

MV VOLTAGE MEASUREMENTS
CAUTION: Do not measure mV voltages if a motor on the circuit
is being switched ON or OFF. Large voltage surges may occur
that can damage the meter.
1. Set the function switch to the green mV position.
2. Press the MODE button to indicate “DC”.or
““AC ”, or in AC range press EXIT for two
seconds and chose ”AC+DC”
Insert the black test lead banana plug into
the negative COM jack.
Insert the red test lead banana plug into
the positive Vjack.
3. Touch the black test probe tip to the
negative side of the circuit.
Touch the red test probe tip to the positive
side of the circuit.
4. Read the mV voltage in the display.
