Continuity Test And Diode Test - Ht Instruments Ht4010 Bedienungsanleitung

Before taking any in circuit resistance measurement,
remove power from the circuit to be tested and discharge
all the capacitors
Rotate the switch on 
1.
at display
2. Pressing the RANGE key to select the correct range or using the
Autorange feature (see § 4.2). If the resistance value under test
is unknown, select the highest range
3. Insert the red test lead plug into V
lead plug into COM jack
4. Connect the two long ends of test leads to the desired circuit
(see Fig. 4) then reading value of resistance will be displayed
5. When "O.L" symbol is displayed, the resistance under test is over
the maximum value that the instrument is able to measure
6. For HOLD function please refer to § 4.2

5.4. CONTINUITY TEST AND DIODE TEST

Before taking any in circuit resistance measurement,
remove power from the circuit to be tested and discharge
all the capacitors
Rotate the switch on 
1.
2. Pushing MODE key and select continuity test. The
shown at display
3. Insert the red test lead plug into V
lead plug into COM jack and perform continuity test on the
object on test (see Fig. 5 – right side). Buzzer emits sound if the
measured resistance value is less about 150
4. Pushing MODE key and select diode test. The "
shown at display
5. Connect the red test leads to the anode of diode on test and the
black test lead on the cathode ones (see Fig. 6 – left side)
6. Displayed values within 0.4V and 0.7V (direct junction) and "O.L"
(reverse junction) are correspondent to a correct result. A "0mV"
value means a shorted device while a "O.L" indication in both
side means a broken device
