Appendix C Using the Battery Option

Operating the Counter from a DC Power Source

When all three segments of the battery annunciator are activated, the battery charge level is at 83% or more. When only two segments are activated, the charge level is approximately 50%, and when only the first segment is activated, the charge level is approximately 17%.

A pair of fully charged batteries in good condition provides enough power to operate the Counter for approximately three hours at 25º C. Various conditions, such as ambient temperature and the measurement configuration, can affect the length of time the Counter can operate from a fully charged set of batteries.

A battery that reads approximately 13.6 VDC when measured with a voltmeter (or the Battery Voltage reading in the menu display) is fully charged. A battery that reads 11 VDC or less is at or near the minimum effective charge level.

Operating the Counter with the display backlight turned off lengthens the time the Counter can operate from the batteries. When operating from battery power, the Counter automatically turns the backlight off after five minutes if no front-panel keys are pushed, no GPIB commands are received, and/or no signal is applied to either input during that period.

Operating the Counter from a

DC Power Source

Counters that have the Battery option can operate from an external DC power source (with or without batteries in the Counter). The external DC power source must supply +11 to +18 VDC at 2.0 A (min.). It must use a

2.1mm coaxial plug, and its DC output plug must be wired so the inner connector is positive and the outer connector is negative. To use an external DC power source, make sure the Main ~ Power switch on the back panel is set to 1 (on), insert the coaxial plug into the EXT DC socket on the back panel as shown in Figure C-2, and turn the Counter on in the normal manner.
