DANGER ●Never make measurement on a circuit above 300V AC or DC. ●Do not attempt to make measurement in the presence of flammable gasses. Otherwise, the use of the instrument may cause sparking, which can lead to an explosion. ●Never attempt to use the instrument if its surface or your hand is wet. ●Do not exceed the maximum allowable input of any measurement range. ●Never open the battery compartment cover when making measurement.

. Preparation for Measurement 5−1 Checking Battery Voltage Set the Function Selector switch to any position other than "OFF". When the display is clear without ■ showing, proceed to measurement. When the display blanks or ■ is shown, replace the batteries according to section 8: Battery Replacement. NOTE The Sleep function automatically turns the instrument off in about five minutes after the last switch operation.
−2 DC Current Measurement 7. Other functions DANGER ●Do not make measurement on a circuit above 300V AC. This may cause shock hazard. ●Do not make measurement with the battery compartment cover removed from the instrument. (1) Set the Function Selector switch to the " A" position DC should be shown on the upper left corner of the display. (2) With the transformer jaws closed and without clamping them onto the conductor, press the Zero ADJ. Button for about one second to zero adjust the display.
8. Battery Replacement WARNING ●To avoid electric shock hazard, never try to replace batteries during measurement. CAUTION ●Do not mix new and old batteries. ●Make sure to install batteries in correct polatiry as indicated in the battery compartment. If the instrumet is powered on, but the display blanks or BATT is shown on the display, replace the batteries (1) Set the Function Selector switch to the "OFF" position.
