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.
