Power supply

7. POWER SUPPLY

Power can be supplied to the measuring instrument in any of the following ways :

3 AA alkaline batteries (included in delivery)

Mains adapter, 12 V, 1 A, with ALMEMO

®

plug ZA 1312-NA7

Power supply cable, electrically isolated (10 to 30 VDC, 0.25 A) ZA 2690-UK

Our product spectrum covers all the appropriate accessories.

7.1 Battery operation and supply voltage monitoring

he device is normally powered by 3 AA alkaline batteries. At a current con-

sumption of on average 25 mA, these last for an operating time of approx. 100

hours. If the display illumination is left switched ON, this operating time will be

reduced to approx. 50 hours. The operating voltage can be checked in the

´

Info

´ menu; this gives you a basis for estimating the remaining operating time.

(see XREF)

As soon as the remaining battery capacity drops to approx. 10%, the battery

symbol

´´µµµµµµµµµ¶

in the status bar of the display will start to flash. If the batteries are

completely discharged, i.e. down to approx. 3V, the device will switch OFF au-

tomatically but measured data already acquired will be saved. (see 7.5)

To replace used batteries first unscrew the battery compartment cover (7) on

the rear of the device. When inserting batteries ensure that their polarity is

correct.

7.2 Mains operation

To power this device from an external source preferably use mains adapter ZA

1312-NA7 (12 V / 1 A); connect this to the DC socket (3).

Please ensure that the mains voltage is correct.

7.3 External DC voltage supply

The

DC

socket (3) can also be used to connect another DC voltage, 6 to 13 V

(minimum 200 mA). ALMEMO

®

connector ZA1012-FS should be used. If,

however, the power supply has to be electrically isolated from the sensors or if

a larger input voltage range (10 to 30 V) is required, then electrically isolated

supply cable ZA 2690-UK must be used. It will then be possible to use the

measuring instrument in a 12-volt or 24-volt on-board supply system.
