80i-110s Instruction Manual 3
INTRODUCING THE CURRENT PROBE
The Fluke 80i-110s is a clamp-on AC/DC Current Probe that reproduces current
waveforms found in modern commercial and industrial power distribution sys-
tems. The probe's performance is optimized for accurate reproduction of currents
at line frequency and up to the 50th harmonic waveform. The 80i-110s is also
compatible with any instrument capable of millivolt measurements. The Current
Probe (shown in Figure 1) provides the following benefits:
• Accurate AC, DC and AC+DC current measurements for Electrical, Electronic
and Automotive applications.
• Shielded for high noise immunity around electronic motor drives and ignition
systems.
• Wide measurement range from 50 milliamps to 100 amps, useful to 10
milliamps.
• Jaw shaped for easy access to cramped spaces.
• Safety-designed 600 volt insuIated BNC - compatible with Fluke ScopeMeter£
test tools, Power Harmonic analyzers, and oscilloscopes.
•Selectable output of 10 millivolts per 1 amp for the 100 A range, and 100
millivolts per 1 amp for the 10 A range.

INSTALLING THE BATTERY
WARNING
TO AVOID ELECTRICAL SHOCK, UNCLAMP THE CURRENT PROBE FROM
ANY CONDUCTOR, AND DISCONNECT THE SCOPEMETER TEST TOOL OR
ANY OTHER MEASUREMENT DEVICE BEFORE INSTALLING OR REPLACING
THE BATTERY.
Atfirstuse,remembertoinstallthebattery.ReferringtoFigure2,usethefollowing
procedure to install the battery:
1. Be sure that you have unclamped the Current Probe from any conductor and
have disconnected the ScopeMeter test tool or any other measurement device.
2. Be sure that the Current Probe is in the OFF position.
3. Locate the battery cover on the handle. (see Figure 2.) Loosen the screw with
a flat-blade screwdriver.
4. Slide the battery cover away from the Current Probe.
5. Install the battery (IEC 6LR61) as shown in Figure 2. Arrange the battery leads
sothattheywillnotbepinchedbetweenthehandlebottomandthebatterycover.
6. Reinstall the battery cover and secure the screw.

USING THE CURRENT PROBE SAFELY
ATTENTION
Carefully read the following safety information before attempting to operate
or service the Current Probe.
•Never use the probe on circuits rated higher than 600V in Installation
Category II (CAT II) or 300V in Installation Category III (CAT III). (See
"Safety Specifications".) Use extreme caution when clamping around
uninsulated conductors or bus bars.
•Keep your fingers off the probe jaws.
•Check the magnetic mating surfaces of the probe jaws; these should be free
of dust, dirt, rust, and other foreign matter.
•Do not use a probe that is cracked, damaged, or has a defective cable. Such
probes should be made inoperative by taping the clamp shut to prevent
operation.
In this Users Manual, a WARNING identifies conditions and actions that pose haz-
ard(s) to the user. A Caution identifies conditions and actions that may damage
the current probe. International electrical symbols used are explained below.
The80i-110sisdesignedtomeet the requirements ofIECPublication 1010 and oth-
er safety standards (see "Safety Specifications"). Follow all warnings to ensure safe
operation.
Use of this equipment in a manner not specified herein may impair the protection
provided by the equipment.
