Safety Information
A Warning identifies conditions and procedures that are dangerous to the user. A
Caution identifies conditions and procedures that could cause Product damage,
equipment under test damage, or permanent loss of data.
Table 1 shows the symbols used on the Product and in this manual.
Warning
To prevent possible electrical shock, fire, or personal injury:
•Use the Product only as specified, or the protection
supplied bythe Product can be compromised.
•Use only correct measurement category (CAT), voltage, and
amperage rated probes, test leads, and adapters for the
measurement.
•Do not touch voltages > 30 V ac rms, 42 V ac peak, or
60 V dc.
•Carefully read all instructions.
•Hold the Product behind the tactile barrier. See Figure 1,
item .
•Do not exceed the Measurement Category (CAT) rating of
the lowest rated individual component of a Product, probe,
or accessory.
•Do not measure current while the test leads are in the input
jacks.
•Do not use the Product around explosive gas, vapor, or in
damp or wet environments.
•Limit operation to the specified measurement category,
voltage, or amperage ratings.
•Do not work alone.
•Do not apply more than the rated voltage, between the
terminals or between each terminal and earth ground.
•Comply with local and national safety codes. Use personal
protective equipment (approved rubber gloves, face
protection, and flame-resistant clothes) to prevent shock
and arc blast injury where hazardous live conductors are
exposed.
•Replace the batteries when the low battery indicator shows
to prevent incorrect measurements.
•The battery door must be closed and locked before you
operate the Product.
•Measure a known voltage first to make sure that the Product
operates correctly.
•Remove all probes, test leads, and accessories that are not
necessary for the measurement.
•Only use probes, test leads, and accessories that have the
same measurement category and voltage rating as the
Product.
•Keep fingers behind the finger guards on the probes.

•Connect the common test lead before the live test lead and
remove the live test lead before the common test lead.
•Remove all probes, test leads, and accessories before the
battery door is opened.
•Do not use and disable the Product if it is damaged.
•Do not use the Product if it operates incorrectly.
•Do not use test leads if they are damaged. Examine the test
leads for damaged insulation, exposed metal. Check test
lead continuity.
•Before each use, examine the Product. Look for cracks or
missing pieces of the clamp housing. Also look for loose or
weakened components. Carefully examine the insulation
around the jaws. See Figure 1, item .
•Examine the case before you use the Product. Look for
cracks or missing plastic. Carefullylook at the insulation
around the terminals.
•Read all safety information before you use the Product.
•Remove batteries to prevent battery leakage and damage to
the Product if it is not used for an extended period.
•Remove the batteries if the Product is not used for an
extended period of time, or if stored in temperatures above
50 °C. If the batteries are not removed, battery leakage can
damage the Product.
Caution
To prevent possible damage to the Product or to equipment
under test, use a thermocouple rated for the temperatures to be
measured. The Product is rated for -10.0 °C to +400.0 °C and
14 °F to 752 °F. The included type-K thermocouple is rated to
260 °C.

To prevent possible damage to the Product or to equipment
under test, do not use abrasive cleaners. They will damage the
case.
Regularly wipe the case with a damp cloth and weak detergent.
To clean the Product Jaw:
1. Examine the jaw-mating surface to make sure it is clean. If there is unwanted
material (including rust), jaw closure will not be correct and there will be
measurement errors.
2. Open the jaws and clean the clamp metal ends with a non-flammable oil and cloth.
Battery Replacement
 Warning
To prevent possible explosion, fire, or personal injury, replace
the batteries when the low battery indicator (B) shows to
prevent incorrect measurements.
Caution
To prevent possible damage to the Product or to equipment
under test:
•Remove batteries to prevent battery leakage and damage to
the Product if it is not used for an extended period.
•Be sure that the battery polarity is correct to prevent battery
leakage.
To change the batteries, see Figure 2:
1. Make sure the Product is off.
2. Turn over the Product to access the battery compartment door screw.
3. Use a flat-head screwdriver to loosen the battery compartment door screw and lift off
the battery compartment door.
4. Replace the two AAA batteries. Make sure to use the correct polarity when you put
the batteries into the battery compartment door.
5. Reattach the battery compartment door.
6. Tighten the battery compartment door screw.

Performance Tests
Warning
To prevent possible electrical shock, fire, or personal injury,
do not go through the performance test procedures unless the
Product is fully assembled.
The performance tests verify the full operation of the Product and measure the accuracy
of each function against Product specifications. If the Product fails a part of the test,
calibration adjustment and/or repair is necessary. See “Calibration Adjustment”.
Before you do the performance tests:
1. Make sure that you have the necessary equipment. See Table 3.
2. Make sure the Product batteries are good and replace them if necessary. See “Battery
Replacement”.
3. Warm up the Calibrator as necessary. Refer to its specifications.
4. Let the temperature of the UUT (unit under test) become stable to room temperature.
Test the Display
To verify that all segments of the display function:
1. With the Product off, push and hold any of the buttons.
2. Turn the rotary switch on while you hold down the button. All of the display
segments are shown. See Figure 3.
If segments of the display are missing, repair is necessary. See “Contact Fluke”.
