Calibration Information

Safety Information

A Warning identifies hazardous conditions and actions that could cause bodily harm or death.

A Caution identifies conditions and actions that could damage the Meter, the equipment under test, or cause

permanent loss of data.

XWWarning

To prevent possible electrical shock or personal injury, follow these guidelines:

•Use this Meter only as specified in this manual or the protection can be compromised.

•Do not use the Meter if it is damaged. Before you use the Meter, examine the case. Look

for cracks or missing plastic. Carefully look at the insulation around the terminals.

•Make sure the battery door is closed and locked before you operate the Meter.

•Replace the batteries when the battery indicator () appears.

•Remove the test leads from the Meter before the battery door on the Meter base is

opened.

•Examine the test leads for damaged insulation or exposed metal. Measure the test leads

for continuity. Do not use if resistance is high or noisy. Replace damaged test leads

before you use the Meter.

•Do not apply more than the rated voltage, shown on the Meter, between the terminals or

between a terminal and earth ground.

•Do not operate the Meter with the battery door removed or the case open.

•Be careful around voltages >30 V ac rms, 42 V ac peak, or 60 V dc. These voltages pose

a shock hazard.

•Use only the replacement fuse specified by the manual.

•Use the correct terminals, function, and range for measurements.

•Do not work alone.

•For current measurements, connect the Meter to the circuit after you remove circuit

power. Always put the Meter in series with the circuit.

•Connect the common test lead before the live test lead and remove the live test lead

before the common test lead.

•Do not use the Meter if it operates incorrectly. Protection can be compromised. If you

are unsure, have the Meter examined.

•Do not use the Meter around explosive gas, vapor or in damp or wet environments.

•Use only specified 1.5-V AA batteries (three in the Meter base and two in the display),

correctly installed, for Meter power.

•Comply with local and national safety requirements when in hazardous locations.

•Only use test leads that have the same voltage, category, and amperage ratings as the

Meter and that are approved by a safety agency.

•Measure a known voltage first to make sure that the Meter operates correctly. If you are

unsure, have the Meter examined.

•Use protective equipment, as directed by local or national authorities when in

hazardous work areas.

•Use only specified replacement parts in the Meter.

•Keep fingers behind the finger guards on the probes.

International Electrical Symbols

WCaution

To prevent damage to the Meter or to the equipment under test, follow these

guidelines:

•Disconnect circuit power and discharge all high-voltage capacitors before you do diode

tests or measure resistance, continuity, or capacitance.

•Use the correct terminals, function, and range for all measurements.

•Before a current measurement, do the fuse test.

Battery Replacement

XWWarning

To prevent incorrect measurements, possible electrical shock, or personal injury, replace

the battery when the battery indicator () appears. If the display shows  , the

Meter will not function until the display module batteries are replaced. If the display shows

 , the Meter will not function until the Meter-base batteries are replaced.

There are two low-battery indicators in the display: one for the Meter base batteries and one for the display module

batteries. Replace the batteries when the low-battery indicator shows.

gcc112.eps

Figure 1. Meter-Base Battery Replacement

To replace the batteries in the Meter base:

1. Turn the Meter off and remove all test leads.

2. Lift the tilt stand up as shown in Figure 1.

3. Turn the battery-door latch with a standard screwdriver until the unlocked symbol () aligns with the arrow.

4. Lift off the battery door.

5. Remove the three AA batteries and replace them with new ones. Use the correct battery orientation.

6. Install the battery door.

Turn the battery-door latch until the locked symbol () aligns with the arrow. When the Meter does not power on,

the Meter-base batteries or display-module batteries can be dead. To find which of the batteries to replace:

1. Dock the display module with the Meter base.

2. Turn the function switch to off and then on.

If the red high-voltage LED on the Meter base flashes, the Meter base batteries are good. Replace the display-

module batteries and turn the Meter on.

Calibration Information

Remove the Display Module

To remove the display module (see Figure 2):

1. Push in on the latches on the sides of the display module.

2. Pull the display module off of the top end of the Meter base.

The Meter base and display module can be a maximum of 10 Meters (30 feet) from each other before the radio

connection is broken. This distance can change if obstacles are between the Meter base and the display module.

There is a radio connection between the display module and Meter base when shows in the display.

When the display module and Meter base lose the radio connection, the display shows dashes and blinks.

Possible causes for this loss are the distance is too far for the environment or the batteries in the Meter base are dead.

To reconnect, decrease the distance between the display module and Meter base.

gcc114.eps

Figure 2. Display Module Separation

To replace the batteries in the display module:

1. Remove the display module from the Meter base. See the “Remove the Display” section.

2. Remove the battery door of the display module as shown in Figure 3.

3. Remove the two AA batteries and replace them with new ones. Use the correct battery orientation.

4. Replace the battery door on the display module.

Dock the display module with the Meter base and turn the Meter on.

Figure 3. Display-Module Battery Removal

Fuse Test

To test the fuse:

1. Set the rotary switch to Ω.

2. Plug a test lead into the vjack and touch the probe to the 10A jack, as shown in Figure 0-4.

If the display shows a resistance value in the range of that shown in Figure 0-4, the fuse is good.

If the display reads 0L, replace the fuse and test again.

If the display shows any other value, have the Meter serviced. See “Contact Information” earlier in this document.

Good fuse: 0.0 Ω to 0.5 Ω

Replace fuse: OL

Fuse Replacement

To replace the fuse:

1. Remove the test leads from the Meter.

2. Remove the display module from the Meter base. See the “Remove the Display Module” section.

3. As shown in Figure 5, remove four screws from the case bottom.

4. Pull the case bottom from the case top.

5. Remove the fuse from its holder and replace it with an 11 A, 1000 V, FAST fuse with a minimum interrupt

rating of 17,000 A. Use only Fluke PN 803293.

To re-assemble the Meter, do the steps above in the opposite sequence.

Cleaning the Meter

Wipe the case with a damp cloth and mild detergent. Do not use abrasives or solvents. Dirt or moisture in the

terminals can affect readings.
