ATD Tools ATD-5544 Instruction Manual

Ac Voltage MEASUREMENT
Set the FUNCTION and RANGE switch to desired ACV
position and connect the test leads across the source or
load under measurement.
Dc Current MEASUREMENT
Set the FUNCTION and RANGE switch to DCA position.
Connect test leads IN to a circuit turn.
Resistance MEASUREMENT
Set the FUNCTION and RANGE switch to desired ohm
range, if the resistance being measured is connected to a
circuit turn o power and discharge all capacitors before
applying probes.
Diode Test
Set the FUNCTION and RANGE switch to 2k/Diode
position, connect test leads ac ross the diode. RED probe to
the anode of the diode and black to the cathode.
Battery Test
Set the FUNCTION and RANGE switch to BATT position.
Connect test leads to the terminals of the battery under test.
Read display value and decide if the battery is OK
MAINTENANCE CAUTION:
Remove from any energized circ uits to avoid shock hazard.
Fuse rarely need replacement and blow almost always as a
result of operator error. If "BAT" appears on display, this
indicates that the battery s hould be replaced. To replace
battery remove screw in the bottom of case - remove the
old and replace with a new one. Be careful to observe
polarity. To replace Fuse (200mA/250V) remove the screw
in the bottom of the case, simply remove the old and
replace with a new one.
