ROTRONIC MBW 973 - Manual (Page 25)

System Configuration 21
Scaling the Output to the Data
With the appropriate configuration window displayed, you may change the data scaling of the
analog output vs. the parameter. Continuing with the example in the previous paragraph,
assume that you wish to have 0 to +1 VDC on the analog output represent 0 to +100 %RH.
Based on the example,
For this field Enter this value
Min Value 0
Max Value 100
Min Voltage 0
Max Voltage 1
Depending on the factory configuration and calibration of your specific 973, it may be equipped
with one of several different output options. Options have included ±1, ±5, or ±10 VDC.
Additionally, some units have been equipped with 4-20 mA outputs. While the most common
option is ±10 VDC (with 16-bit resolution), many older units where equipped with ±5 VDC (with
12-bit resolution). You may wish to experiment with your 973 output to determine which
configuration you have.
Voltmeter Connections
Analog output connectors are clearly identified on the instrument back panel. With the analog
output parameters selected and properly scaled, connect a cable between the analog output
and a voltmeter. Pre-wired cables are available. If you wish to make your own cables, see
Analog Outputs on page 23 for pin-out information.
