2.2. Setup for Operation
The instrument is to be connected to main powers either by a connector or by
using the terminals inside the housing. The correct voltage is marked on the
type label you find on one side of the housing. Do not use voltages other than
the marked one! Severe damage would be the result of applying the wrong
voltage.
If a type 72B. instrument with screw terminals is used, the cross section of your
conductors should meet the dimensions of 0.5 up to 1.5 mm 2 (AWG 16 to AWG
20) You will find these terminals on the ground PC-board after opening the
housing by turning the four screws (quick-release types) with a screwdriver to
the left.
Please take care that cable diameter corresponds with PG-dimension and so
will guarantee a dense screwing. During operation the housing of the instrument
should be closed.
2.3. Instructions for Dispatch
If there any problems you are not able to correct, we ask you to contact our
technical department or to return the instrument with a short description of the
fault. When returning please do not forget:
a) to add the description of faults
b) to pack the instrument safely in a cardboard box and fill up
holes with soft packing material to avoid damage.
3. Dialog orientated Software
3.1. Program Structure
For simplier operation, the software of type 72 transmitters is devided into 4
main parts which are:
a) "RUN" = normal operation for measuring Humidity and Temp.
b) "LIST" = listing all parameters used for operation
c) "CALIB" = calibration of a sensor probe
d) "CONFIG" = setup or change of parameters as:
ranges of humidity and temperature,
lower and upper limits of analog outputs,
dimensions of humidity and temperature values
Each of this main programs is devided into submenus to create a better
overview of its functions and to simplify the operation.
3.2. Pushbutton Operation:
The four pushbuttons are located on the display board and can only be seen
after removing the cover of the transmitter housing. Opening of the cover is
