Using Meter For Temperature Readings; Clamp-On Ammeter - Maytag LAT2300 Service Manual

Using Meter For Temperature
Readings
(50°F. to 300°F.)
Washer - Water temperature readings
are most accurate when the temper-
ature probe is lowered partially into a
full tub of water (HOT-COLO-WARM).
SET UP METER FOR USE AS FOLLOWS:
1. Turn selector knob to TEMP.
2. Insert black negative lead of temper-
ature probe into black socket
marked (-) negative.
3. Insert red positive lead of temper-
ature probe into red socket marked
(+) positive.
4. To calibrate meter, touch black plug
from red positive Iead to black nega-
tive lead and turn calibration dial
until needle aligns with CAL.
5. Probe is ready to use - read blue
scale on meter face marked TEMP.
Clamp-On Ammeter
16001145
Each circuit in an appliance has a
"normal" current draw which is an indi-
cation of the performance of that circuit.
Current draw levels, less than or more
than normal, give clues to malfunctions.
The clamp-on ammeter measures these
currents without breaking the circuit by
measuri ng the strength of the magnetic
field developed around each conductor.
Current is read by separating the con-
ductors and clamping the jaws of the
ammeter around each conductor on
which current is to be read. Low
amperage readings indicate problems
such as damaged heating elements,
etc. High amperage readings indicate
the unit being tested is operating under
an increased mechanical or electrical
load.
Note: Overloads on a circuit breaker
or fuse can be traced to the product
being tested or the ci rcuit breaker (or
fuse) by checking the product's current
draw. If the amperage reading is less
than the breaker readi ng, the breaker
or fuse box is at fault.
Note: A wattmeter reading will provide
better information than an ammeter as
it gives a more accurate indication.
