2.4 OPERATION AND CONTROLS
This section instructs you in the operation of the instrument. It describes battery
and/or AC adaptor installation and the controls and functions of the different control
loops and operating modes.
2.4.1 Battery/AC Adaptor Installation
The instrument may be powered by batteries or an AC adaptor. Battery power is sup-
plied by 4 “AA” batteries. The batteries are located in the base of the handle. AC
power is supplied by an optional AC power adaptor (DIN VDE 0551 approved).
NiCad batteries can also be used, but battery life will be substantially reduced. Figure
2-3 shows the location of the battery compartment, battery orientation, and the loca-
tion of the AC adaptor power connection.
Table 2-1 shows approximate battery life (for alkaline batteries) for various operating
conditions.
Notes: Battery types and brands vary in length of usable life. The values in Table 2-1 are
approximate for new alkaline batteries. The instrument will continue to read accurate-
ly up to 4 hours after the low battery icon displays if the laser and backlight are off.
Remove the batteries if the unit is not used for long periods of time.
220 VAC adaptors must have DIN VDE 0551 approval to be used with IEC Class 2
laser units.
