Measuring Capacitance; Automatic Power-Off - USAG 076 A Manuel D'utilisation

Continuity Test
1. Connect the black test lead to the "COM" terminal and the red test lead to the
"
2. Set the range switch to "
symbol " " appears on the display.
3. Connect the test leads to the circuit to be measured.
4. If the circuit resistance is less than about 30Ω, the built-in buzzer will sound.
Note: Before test, disconnect all power to the circuit to be tested and discharge all
capacitors thoroughly.
Diode Test
1. Connect the black test lead to the "COM" terminal and the red test lead to the
"
2. Set the range switch to "
" " appears on the display.
3. Connect the red test lead to the anode of the diode to be tested and the black test lead to
the cathode of the diode.
4. The display shows the approximate forward voltage drop of the diode. If the connection
is reversed, "OL" will be shown on the display.

Measuring Capacitance

1. Connect the black test lead to the "COM" terminal and the red test lead to the
"
1. Set the range switch to
3. If the display doesn't read zero, press the "REL" button.
4. Connect the test leads across the capacitor to be measured.
5. Wait until the reading is stable, then read the reading on the display. (For high
capacitance measurements, it may take about 30 seconds for reading to stabilize.)
Note: Before measurement, make sure that the capacitor to be measured has been
discharged thoroughly.
Measuring Frequency and Duty Cycle
1. Connect the black test lead to the "COM" terminal and the red test lead to the
"
2. Set the range switch to Hz/% position. Then press the "Hz%" button to select frequency
measurement or duty cycle measurement, the display will show the corresponding unit.
3. Connect the test leads across the source or load to be measured.
4. Read the reading on the display.
Note:
1. For frequency measurements, the voltage of the input signal must be between 1V rms
and 20Vrms.
2. For duty cycle measurements, the voltage of the input signal must be between 3Vp-p and
10Vp-p. If the frequency of input signal is too low, the reading's stability will decrease.
3. For both frequency and duty cycle measurements, if the voltage exceeds the specified
range, the error of reading maybe out of the specified accuracy range.

Automatic Power-off

The display will blank and the meter will go into Sleep mode if you have not turned the
rotary switch or pressed button for about 15 minutes. To arouse the meter from Sleep,
just press a button.
