Fluke 27/FM - Multimeter Safety and Precautions

Battery Installation and Replacement
WARNING
TO AVOID ELECTRICAL SHOCK OR DAMAGE TO THE METER, DO NOT
APPLY MORE THAN 1000V BETWEEN ANY TERMINAL AND EARTH GROUND.
WARNING
TO AVOID ELECTRICAL SHOCK, USE CAUTION WHEN WORKING ABOVE
60V DC OR 25V AC RMS. SUCH VOLTAGES POSE A SHOCK HAZARD.
o
Disconnect the live (hot) test lead before disconnecting the common
test lead.
o
Follow all safety procedures for equipment being tested. Disconnect
the input power and discharge all high-voltage capacitors through a
protective impedance before testing in the
 and Ho , 4* functions.
o When making a current measurement, turn the power off before
connecting the'DMM in the circuit.
o
Check DMM fuses before measuring transformer secondary or motor
winding current. An open fuse may allow high voltage build-up,
which is potentially hazardous.
WARNING
TO AVOID ELECTRICAL SHOCK, REMOVE THE TEST LEADS AND ANY
INPUT SIGNALS BEFORE REPLACING THE BATTERY OR FUSES.
BATTERY INSTALLATION AND REPLACEMENT
The meter is powered by a single 9V battery (NEDA 1604, 6F22, or 006P).
Referring to Figure 2, use the following procedure to install (and replace)
the battery.
1.
Disconnect test leads from any live source, turn the rotary switch
to OFF, and remove the test leads from the input terminals.
2. Lift the instrument stand on the back of the Fluke 27/FM, then
remove the four (#6 X 32) screws from the battery cover.
3.
Pull the battery cover straight out from the back of the meter.
(A coin-slot in the side of the battery cover facilitates removal.)


Snap the battery connector to the terminals on the battery, then
slide the battery into the battery holder. Slip each battery lead
into the slot in the holder as shown in Figure 2.
5. 
Insert the battery holder/cover into the meter, then start the four
screws removed in step 2. Press firmly on the battery cover while
tightening the screws in a diagonal pattern.
