10. Programming With Programming-Menus
Programmed Analog Value Output
The analog value (Output to A1) can also be programmed, manually or via in-
terface, in a range from -12000...+20000 digits (see manual 6.10.7). Depen-
ding on the analog output the following output signals are available:
Voltage output
-1.2 ... +2.0 V
0.1mV/Digit
Voltage output
-6.0 ... +10.0 V
0.5mV/Digit
Current output
0.0 ...20.0 mA
1µA/Digit
Set analogue channel to programmed output with:
<CLR>
Analogue channel: M--
Output of 2.5V using the 10V output = 5000 digits:
Analogue value:+05000
switching back to the meas. channel by using the key:
<OFF>
switching back to the previous programming value:
<ON>
10.7 Menu Power Supply
Power for the measuring instrument is normally
supplied from three AA battery cells, either
standard or rechargeable. The
POWER SUPPLY
menu provides an estimation of the battery's re-
maining operating time in the form of a current
voltage display. At 3.5 volts the battery symbol
in the status line starts to flash and at 3.1 volts
the device switches off automatically. The cur-
rent charge status cannot be displayed more
exactly than this because of the different types
of battery cell available.
To power the sensors a selectable sensor vol-
tage is generated (approx. 6, 9, or 12 volts).
With sensors that draw a lot of current but manage with relatively low voltage,
the ideal sensor voltage selection can save a lot of energy.
Setting the desired Sensor Voltage:
Sensor voltage set: 9.0 V
Display of actual sensor voltage:
Sensor voltage act: 9.1 V
If a mains adapter is connected, the sensor
voltage will always be over 9V:
Mains adapter:
9.3 V
The max. admissible current is also displayed:
Maximum current:
1.0 A
Our range of accessories includes a rechargeable battery set ZA2690-AS,
comprising three NiMH 1.6-Ah accumulators and an intelligent charge adapter.
These rechargeable batteries are coded in such a way that they can be reco-
gnized and correctly recharged in the device. They can be charged up quickly
and easily irrespective of their current charge status at any time. The charge
adapter regulates the charging current according to the maximum admissible
current of the mains adapter and the capacity of the rechargeable batteries in
such a way that the recharging process can be completed as quickly as possi-
ble. However, in normal operating conditions the current is reduced in order to
