read the display value.
Note:
The tested capacitor should be discharged before the testing
procedure. Never apply voltage to the “Cx” input socket, or serious damage
may result.
5.5 FREQUENCY MEASUREMENT
1) Set the function range switch at the required “Hz” position.
2) Connect test leads to measuring points and read the display value.
Note:
Do not apply more than 250V rms to the input. Indication is possible a
voltage higher than 100V rms, but reading maybe out of specification.
5.6 TEMPERATURE MEASUREMENT
1) Set the function range switch at the “TEMP” position.
2) Be sure the polarity of the thermocouple, put the cold end (free end) of
the thermocouple sensor into the temperature testing holes.
3) The working end (testing end) on or inside the object being tested.
4) The value of the temperature is shown on the display in degrees
centigrade (°C).
Note:
a) The testing temperature is displayed automatically when the
thermocouple is put into the testing holes.
b) The surrounding temperature is shown when the circuit of the
sensor is cut off.
c) The limit temperature measured by the thermocouple given
together with the instrument is 250°C, 300°C is acceptable within
short period.
5.7 DIODE & CONTINUITY TEST
1) Set the function range switch at the “
” position.
2) Connect the black test lead to “COM” terminal and red test lead to
“V/OHM” input terminal (Note: the polarity of the red test lead is “+”).
3) This range with “AUDIBLE CONTINUITY TEST” function. Built-in
buzzer sounds if the resistance between two probes is less than 30±10
Ω
.
4) Connect the test leads across the diode and read the display value.
Note:
a) When the input is not connected, i.e. at open circuit, the figure “1”
will be displayed.
b) Test condition: Forward DC current approx.1mA. Reversed DC
