HOLD

The hold function freezes the reading in the display. Press the HOLD key momentarily to activate or
to exit the hold function.

AUTO POWER OFF

The auto off feature will turn the meter off after 15 minutes.

LOW BATTERY INDICATION

The icon will appear in the lower left conner of the display when the battery voltage becomes
low. Replace the battery when this appears.

WRONG CONNECTION INDICATION

The icon will appear in the upper right conner of the display and the buzzer will sound
whenever the positive test lead is inserted into the 10A or uA/mA input jack and a non-current
(green, black or red) function is selected. If this occurs, turn the meter off and reinsert the test lead
into the proper input jack for the function selected.
