14.3 DETERMINATION OF THE TWO MEASURING RANGES TO BE SELECTED ON
THE INSTRUMENT
In order to minimize operating errors, the
PMA45K1
provides the possibility to determine two measur-
ing ranges that may then be selected via a switch on the instrument.
The selection of measuring range 1 and 2 is made via two jumpers on the below illustrated plate. On
the photo, you can see that for range 1 the 1 % measuring range has been selected and for range 2
the 2.5 % measuring range. The selected measuring ranges refer only to the mA-outlet. The digital
indication is always in the 100.00 vol% O
2
measuring range.
Via the external measuring range selection, all measuring ranges are available.
