Before using verify that the insulation on test leads is not damaged and/or the leads’ wire
is not exposed.
Always be careful when working with voltages above 60V D or 30V A rms, keep fingers
behind the probe barriers while measuring.
Before stir the transform switch to change functions, disconnect test leads from the
circuit under test.
Never measure any of resistance，capacitance, diode or continuity measurements on live
circuits.

4. Battery replacement
If the sign “ ” appears on the LCD display, it indicates that the battery should be replaced.
Remove screws on the back cover and open the case. Replace the exhausted battery with new
batteries. (1 x 9V battery NEDA 1604, 6F22 or equivalent)
