Important Safety Information (cont.)
Electric shock and re hazard:
• Do not expose this unit to rain or moisture.
• Do not use the unit if it is wet or damaged.
• Clamp meter, leads or any other clamp accessory, when used to make a
measurement, create a System. The System is rated for CAT IV 600V
when using the leads or accessories provided with the meter. The System
CAT and voltage rating is limited by the lowest rated component in the
System when using leads or accessories not provided with the meter.
• Inspect the leads or accessory before use. They must be clean and dry, and the
insulation must be in good condition. Do not use the test lead if the contrasting
inner layer of insulation is visible.
• Use this unit for the manufacturer’s intended purpose only, as described in this
manual. Anyotheruse can impair the protection provided by the unit.
Failure to observe these warnings could result in severe injury or death.
Electric shock hazard:
• Do not apply more than the rated voltage between any two input terminals, or
between any input terminal and earth ground.
• Keep hands and ngers below the barriers on the leads and the clamp meter body.
Failure to observe these warnings could result in severe injury or death.
Electric shock hazard:
• Do not operate with the case open.
Failure to observe these warnings could result in severe injury or death.
Electric shock hazard:
• Unless measuring current, shut off and lock out power. Make sure that all capacitors
are discharged. Voltage must not be present.
• Using this unit near equipment that generates electromagnetic interference can
result in unstable or inaccurate readings.
Failure to observe these warnings could result in severe injury or death.
Electric shock hazard:
• Do not attempt to repair this unit. It contains no user-serviceable parts.
• Do not expose the unit to extremes in temperature or high humidity. Refer to
“Specications.”
Failure to observe these precautions may result in injury and can damage the unit.

Identication
1. Rogowski Coil - The measurement coil of ex clamp meter
2. Clamp Lock – Turn the knob counter clockwise to unlock the clamp; turn clockwise
to lock the clamp
3. Coil Support - Fixes coil to the clamp meter
4. Power Indicator – The LED will be illuminated when the clamp meter is powered on
and in normal operation. The LED will ash when the batteries are low.
5. Range Switch – Select the appropriate current range for the application; Ranges
are 30A, 300A and 3000A
6. Output Voltage Description – Lists the output voltage resolution for a given range.
All voltages are AC.
7. Output Voltage Terminal – Outputs voltage to an AC voltage measuring device.

Operation
Electric shock hazard:
Contact with live circuits could result in severe injury or death.
Keep your hands away from the Rogowski coil and conductor to be measured.
Disconnect all power supplies from the device before measurement. When measuring
uninsulated conductors, do not power on the wire to be tested until the meter has
safely clamped the wire.
FC-110
Figure 2
1. Turn off the clamp meter as well as the conductor being measured.
2. Unlock the clamp according to Figure 3
3. Use the measuring head to wrap around the conductor to be measured and lock it
in place. (Only one wire can be tested at a time; See Figure 4)

Operation (cont.)
4. Turn on the clamp, then turn on the conductor.
5. Connect the clamp meter to an AC Voltage measuring device with a resolution
of at least 1mV.
6. Read the value displayed on the AC voltage measuring device. If the current to be
measured is over the range, a value greater than 3V will display on the AC voltage
measuring device. Please select the appropriate range. (30.00A/300.0A/3000A)
7. Improper operation examples:
a. Do not test more than one conductor at a
time as shown in as shown in Figure 5
b. Do not attempt to twist, bend, or wrap the coil
of the CMF-110/118 as shown in Figures 6, 7, and 8.
c. Do not attempt to pull on or apply a force to the
coil of the CMF-110/118
