3. Observe the readout. Press the next lower-value
RANGE push buttons
as necessary to obtain a proper
readout (see Table
4).
NOTE
If no voltage is applied to the DM44 while in the
20 volt to 1.2 kilovolt ranges, the readout is 0000,
and individual readout elements may blink. Also,
noise picked up
by the meter leads may increase the
readout while in the 0.2 volt and 2 volt
ranges.
A blinking readout for any RANGE value selected
indicates an overrange condition. The next higher
RANGE value should be selected.

TEMPERATURE
The maximum safe voltage on the measurement
surface
is ±100 volts (de + peak ac) above chassis
ground.
The sensor tip is fragile and may break if dropped or
subjected to excessive stress. Force exerted on the
sensor tip should
not exceed 20 pounds.
If the readout exceeds -55" Cor +150° C, imme-
diately remove the probe
to prevent probe damage.
1. Press the TEMP (°C) FUNCTION push button (see
Figure
10).
2. Apply the temperature probe to the device whose
temperature
is being measured. Refer to the probe's
Instruction Manual
for specific instructions regarding
probe use.
3. Observe the readout. Refer
to Table 5 to convert the
readout from degrees Celsius to degrees Fahrenheit.
