NOTE:The DC power option includes a low voltage indicator. The low

voltage indicator needs to be plugged into the instrument with the battery

option plugged in to the low voltage indicator. The low voltage indicator

light illuminates when the voltage drops below a safe operating range. The

instrument should not be used for measuring when the low voltage light is

illuminated. Recharge the battery to an acceptable level before taking

measurements.
