Auto/Manual Range
To select manual range, repeatedly press "rAngE" key until the display shows the desired range. The range steps upward
as you press the "rAngE" key. The meter will go back to auto range mode when you press "rAngE" key for more than
2 secs. one cannot select manual range mode when measuring capacity and temperature. If "oL" appears on the display,
immediately set it to a higher range.

BATTEry rEpLACEMEnT
1. When the battery voltage drops below the operation range, the "
" symbol appears on the LCD-display and the bat-
tery needs to be replaced.
2. Before changing the battery, set the selector switch to "oFF" position. open the cover of the battery cabinet with a
screwdriver.
3. replace the old batteries with the same type (1.5V AA) batteries.
4. Close the battery cabinet cover and fasten the screws.
FusE rEpLACEMEnT
1. This meter is provided with a 0.5A/250V fuse to protect the current measuring up to 400mA and a 10A/250V fuse to
protect the measuring for “A “ range.
2. Ensure the instrument is not connected to any external circuit. set the selector switch to "oFF” position
and remove the test leads from the sockets.
3. open the cover of the battery cabinet using a screwdriver.
4. remove the old fuse from the holder and replace it with the same type of fuse (5x20 mm 0.5A/250V or 6x30 mm
10A/250V).
5. Close the battery cabinet cover and fasten the screws.
MAInTEnAnCE
1. Before opening the battery cover, disconnect both test leads and never use the meter when the battery
cover is open.
2. Do not touch the circuit board without proper static protection.
3. If the meter is not going to be used for a longer period of time, take out the batteries and do not store the meter in an
environment with high temperature or humidity.
4. repairs or servicing not covered in this manual should only be performed by qualified personnel.
