AXIOMET AX-T520 Расширенная инструкция онлайн [12/13] 527868

Maximum Open Circuit Voltage: 700mV (3V for 200MΩ range).

Note: On 200MΩ range, if short input, the display will read 1MΩ, this 1MΩ should be subtracted

from measurement results.

Overload Protection: 250V dc or 250V ac rms

4.5 DIODE/CONTINUITY

Range Description

Diode Shows the approximate forward voltage drop

Continuity The built-in buzzer will sound, if the resistance under test is less than

about 70Ω

Overload Protection: 250V dc or 250V ac rms

5. BATTERY &

& FUSE REPLACEMENT

If the sign“ ”appears on the LCD display, it indicates that battery should be replaced.

Remove screws on the back cover and open the case (see the right photo). Replace the exhausted

battery with a new one.

The fuse rarely needs replacement and blows almost always as a result of the operator’s error.

Open the case as mentioned above, and then take the PCB out from the front cover. Replace the

blown fuse with same ratings.

WARNING

Before attempting to open the case, be sure that test leads have been disconnected from

measurement circuits to avoid electric shock hazard.

For protection against fire, replace fuse only with specified ratings: F 200mA/250V
