AXIOMET AX-T520 Расширенная инструкция онлайн [7/13] 527868

3.2.4 If you need data hold when measuring, you can put on “HOLD”, it will hold the reading;

if you put on the button again, data hold will not continue.

3.2.5 When only the figure “1” is displayed, it indicates overrange situation and the higher range

has to be selected.

3.3 TESTING DIODE/CONTINUITY

3.3.1 Connect the black test lead to the COM jack and the red test lead to the V/Ω jack.

(NOTE: The polarity of red lead connection is positive“ + ”)

3.3.2 Set the rotary switch at position and connect the red lead to the anode, the black lead to

the cathode of the diode under testing. The meter will show the approx. forward voltage drop of

the diode. If the lead connection is reversed, only figure “1” will be displayed. If continuity exists

(i.e. resistance less than about 70Ω), a built-in buzzer will sound.

3.4 MEASURING RESISTANCE

3.4.1 Connect the black test lead to the COM jack and the red test lead to the V/Ω jack.

(NOTE: The polarity of red lead connection is positive“”)

3.4.2 Set the rotary switch at desired Ω range position and connect test leads across the resistance

under measurement. Read the LCD display.

NOTE:

1. For resistance above 1MΩ, the meter may take a few seconds to stabilize reading.

2. When the input is not connected, i.e. at open circuit, the figure “1” will be displayed for the

overrange condition.

3. When checking in circuit resistance, be sure the circuit under test has all power removed and all

capacitors are full discharged.

4. At 200MΩ range display is 10 counts when test leads are shorted. These counts have to be

subtracted from measuring results. For example, when measuring 100MΩ resistance, the reading

will be 101.0 and the correct measuring result should be 101.0 - 1.0 = 100.0 MΩ.

3.5 TESTING BATTERY

3.5.1 Connect the black test lead to the COM jack and the red test lead to the V/Ω jack.

3.5.2 Set the rotary switch at the desired “BAT” range position and connect test leads across the

battery.
