Safety
3.1 General Safety Information
This user 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.
The meter protection rating, against the users, is double insulation per UL/
IEC/EN61010-1 Ed. 3.0, IEC/EN61010-2-033 Ed. 1.0, CAN/CSA C22.2 No.
61010-1 Ed. 3.0, IEC/EN61010-2-032 Ed. 3.0 & IEC/EN61010-031 Ed. 1.1:
Measurement Category IV 1000V AC & DC.
Per IEC61010–1 OVERVOLTAGE CATEGORY
OVERVOLTAGE CATEGORY II (CAT II) is for equipment intended to be supplied from the building wiring. It applies both to plug-connected equipment
and to PERMANENTLY CONNECTED EQUIPMENT.
OVERVOLTAGE CATEGORY III (CAT III) is for equipment intended to form
part of a building wiring installation. Such equipment includes socket outlets,
fuse panels, and some MAINS installation control equipment.
OVERVOLTAGE CATEGORY IV (CAT IV) is for equipment installed at or near
the origin of the electrical supply to a building, between the building entrance
and the main distribution board. Such equipment may include electricity tariff
meters and primary over-current protection devices.
3.2 Safety Terms Used 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.
3.3 Warning and Caution Statements
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.

Safety
WARNING
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. Before and after hazardous voltage measurements, test the voltage function on a known source such as line voltage to determine proper meter functioning.
WARNING
Keep hands/fingers behind the hand/finger barriers (of the meter and the test leads) during
measurement. Inspect test leads, connectors, and probes for damaged insulation or exposed metal before using the instrument. If any defects are found, replace them immediately. Use only the test leads provided with the equipment (or UL Listed probe assemblies
rated CAT IV 1000V or better).
WARNING
The accompanied test probe assembly meets UL/IEC/EN61010-031 Ed. 1.1 to the same
meter ratings or better. IEC 61010-031 requires exposed conductive test probe tips to be
≤ 4mm for CAT III & CAT IV ratings. Refer to the category markings on your probe assemblies as well as on the add-on accessories (detachable Caps or Alligator Clips, etc.), if any,
for applicable rating changes.
WARNING
This Clamp meter is designed for clamping around or removing from non-insulated, hazardous live conductors. Nonetheless, individual protective equipment must be used when
hazardous live parts in the installation, where the measurement is to be made, could be
accessible.
WARNING
Remove test leads from the meter before taking clamp measurements.
CAUTION
Disconnect the test leads from the test points before changing meter functions.
CAUTION
Do not use the device for a procedure that it is not intended for. This can cause damage to
the protection built into the instrument.

Meter Operation
NOTE
Before operating the device, you must read, understand, and follow all instructions, dangers,
warnings, cautions, and notes.
NOTE
When the meter is not in use, the function switch should be set to the OFF position.
NOTE
When connecting the probe leads to the device under test, connect the negative lead before
connecting the positive lead. When removing the probe leads, remove the positive lead before removing the negative lead.
NOTE
Before and after hazardous voltage measurements, test the voltage function on a known
source (such as line voltage) to determine proper meter functionality.
5.1 Powering the Meter
Set the function switch to any position to power the meter ON.
If the low battery voltage warning is displayed, or if the meter does not power
ON, replace the batteries. See Section 6, Maintenance, for battery replacement details.
5.2 Auto Power OFF (APO)
The APO feature switches the meter OFF after approximately 34 minutes of
inactivity. The meter will beep to alert you when it is about to power OFF, press
the MODE button to extend the APO time. If the meter powers OFF, turn the
rotary switch to the OFF position first and then to an operational position to
switch back ON.
5.3 Automatic and Manual Ranges
The meter uses automatic ranging by default. To manually select a measurement range, short press the RANGE button to exit the Auto mode. Subsequent, short presses will step through the available ranges. Long press the
RANGE button to return to the Auto Range mode. When the Auto Range
mode is active, the Auto Range symbol is displayed.

Press the HOLD button again to return to normal operation. The H icon will
appear when the display hold function is engaged.
5.6 Display Backlight
Long press the backlight button
to turn ON the display backlighting. Long
press again to switch the backlight OFF. The backlight switches OFF automatically after approximately 25 seconds to conserve battery energy.
5.7 AC and DC Voltage Measurements

Meter Operation
5.8 LoZ Voltage Measurements
WARNING
In LoZ mode, the input impedance increases quickly from the initial 2.5kΩ to a few hundred kΩ’s on high voltage signals. Peak initial load current, while testing 1000 V AC for example, can be as high as 566 mA (1000 V x 1.414 / 2.5kΩ), decreasing to roughly 3.37
mA (1000 V x 1.414 / 420kΩ) within a fraction of a second. Do not use LoZ mode on circuits that could be damaged by such low input impedance. Use the standard high input impedance voltage modes to minimize loading on such circuits.
CAUTION
Use caution when the measured voltage is greater than 30V DC or AC rms.
LoZ Voltage measurements eliminate the affects of ‘ghost’ voltages. The procedure for taking LoZ Voltage measurements is essentially the same as for
taking standard Voltage measurements, the only difference is that for LoZ
Voltage measurements you select the LoZ rotary switch position and you must
take into consideration the effect low impedance will have on circuitry that you
test (read Warning statement above). Refer to the previous section for other
Voltage measurement details.
When you turn the rotary dial to the LoZ position, the display will show ‘auto’
indicating that the CM94 will automatically detect the measured signal as AC
or DC.
5.9 Low Pass Filter (VFD) AC Voltage Measurements
CAUTION
Use caution when the measured voltage is greater than 30V DC or AC rms.
Select the VFD mode using the rotary selector switch.
The VFD feature eliminates high frequency noise in AC voltage measurements by means of a low pass filter. The VFD mode is designed for variable
frequency drive measurements. The VFD icon will appear on the display in
this mode. The procedure for taking VFD Voltage measurements is identical
to the procedure for taking standard Voltage measurements. Refer to the previous sections for Voltage measurement details.

Meter Operation
5.10 Current Clamp Measurements
WARNING
Do not measure current on a circuit if the voltage increases to more than 1000 V. This can
cause damage to the instrument and can cause injury to persons.
WARNING
Do not use the meter to measure current above the rated frequency. This may cause the
magnetic circuits in the jaws to reach hazardous temperatures.
WARNING
Disconnect the test leads from the meter before taking Clamp measurements.
Clamp Measurement Considerations
• Press the jaw trigger to open the jaws and then clamp around the conduc-
tor(s) of only one pole of a circuit.
• Ensure that the jaws are completely closed. Enclosing conductor(s) of
more than one pole of a circuit may result in differential current
measurements.
• Align the conductor(s) to the jaws using the conductor align icons on the
clamp jaws.
• Adjacent current-carrying devices such as transformers, motors and con-
ductor wires may affect measurement accuracy.
