Setting the Measuring Range (Optional)
The transmitter with 4 measuring ranges can be adapted to the measuring
assignment in question. The teaching of 4 measuring ranges into the appliance has
been undertaken by the manufacturer. The switches 1 and 2 of SW can be used to
select the measuring range in question before the transmitter is switched on.

The limiting values of the measuring ranges are noted on the nameplate of the PS27.
Display-optional appliances indicate the limiting value of the selected measuring
range for 1.5 seconds after being switched-on. The appliance should be re-zeroed
following any measuring range change-over. This is because the amplification
change-over may produce offset voltages
