1) Discharge capacitor(s) before making capacitance measurements. Large value
capacitors should be discharged through an appropriate resistance load.
2) Using BeepLit
TM
Diode or Capacitance function in a live circuit will produce false
results and may damage the meter. In many cases, the suspected component(s) must
be disconnected from the circuit to obtain an accurate measurement reading.
Temperature: T1 (Models 789 & 786 only); +T2 (Model 789 only)
T1 inputs are made via the input terminals V-COM. Press SELECT button momentarily
can toggle between °C (Celsius) and °F (Fahrenheit) readings when enabled. Last
selection will be saved as power up default for repeat measurement convenience.
Additional T2 inputs are made via the input terminals - . Press RANGE (T1-
T2) button momentarily to select T1, T2 and T1-T2 in sequence.

Enabling °F and/or °C readings
1) Enabling both °F and °C readings: Press-and-hold EF button to power on the
meter. The meter displays “C-F” to acknowledge both °F and °C readings are enabled.
2) Enabling °C readings only: Repeat step #1 when needed. Turn on the meter to
temperature function. Select readings in °C and then turn the meter off. Press-and-hold
CREST button to power on the meter again. The meter displays “C” to acknowledge °C
readings only is enabled.
3) Enabling °F readings only: Repeat step #1 when needed. Turn on the meter to
temperature function. Select readings in °F and then turn the meter off. Press-and-hold
CREST button to power on the meter again. The meter displays “F” to acknowledge °F
readings only is enabled.
