Note:
1-
This function is available to primary functions: DCV, ACV,
Hz, Dwell, Fuel injection detector, & Duty cycle.
2- When trigger level selection is required for advanced
applications, use main display RPM function. See (4.3.6)
for more details.
4.3.3 TEMPERATURE Function

DIODE TEST function
Temperature Probe
•
Set rotary switch to
position
•
Press SELECT button momentarily two times to select temperature
function.
•
Without any temperature probe plugged into the input terminals
(detect automatically by the meter), the secondary digital display
displays the meter internal temperature reading in °C & °F
alternatively.
•
Insert the banana plug type-K temperature bead probe (standard
accessory) with correct
polarities. Positive (
) plugs into
jack where negative (
) plugs into COM input jack. You can
also use a plug adapter (optional accessory) with banana pins
to type-K socket to connect other standard type-K mini plug
temperature probes.
•
Touch the end of the thermo probe to the measurement surface
and observe the digital display with °C in the main display, and °F
in the second display.
•
Set rotary switch to
.
•
Insert red (
) test lead into
jack and black (
) test lead into
COM input jack.
•
Connect the test leads as shown and observe the digital display.
•
Normal forward voltage drop (forward biased) for a good silicon
diode is between 0.400V to 0.900V. A reading higher than that
indicates a leaky diode (defective). A zero reading indicates
a shorted diode (defective). An ‘
OL
’ indicates an open diode
(defective).
•
Reverse the test leads connections (reverse biased) across the
diode.
•
The digital display shows ‘
OL
’ if the diode is good. Any other
readings indicate the diode is resistive or shorted (defective).

CAUTION
: Maximum Input Voltage for this function is 600 Vrms
do not exceed this rating to avoid personal injuries or
damage to the instrument. Also ensure there is no
power applied to the component or circuit and all
capacitors are discharged.
