HECKING

After removing the cover (and the Display Module if there is any) the actual loop current can be measured with an accuracy of 0.5% by connecting an voltmeter
(in the range of 200 mV) to the points indicated on the drawing above

4.

PROGRAMMING

The

DMSP400 and DMSP500

can be programmed by the following two ways:

•

Programming

without Display Module see 5.1.

Assignment of the levels to the 4 and 20 mA current output, error indication by the analogue signal and damping can be set.

•

With the

DISPLAY MODULE

, see 5.2.

All features of the unit can be set, such as measurement configuration and optimisation, 32-point linearisation, dimensions for 11 tanks with different
shape and for 21 different open channels (flume, weir, etc).

Devices with the type number

DMSP400 and DMSP500

are already equipped with the Display Module.

The DMSP400 and DMSP500 is fully operational without the Display Module. The Display Module is only needed for programming and/or displaying
measurement values.

The unit will measure during programming in accordance with the previous parameters. The new, modified parameters will only be effective after
returning to the Measurement Mode

If the transmitter is left in Programming Mode by mistake, it will automatically return to Measurement Mode after 30 minutes and will operate with the parameters
entered during the last completed programming.

The DMSP400 and DMSP500 will be delivered with the following

Factory Default

:



Current output, display and bargraph: LEVEL



Current output and bargraph proportional to the level



4 mA: assigned to the minimum level 0%



20 mA: assigned to the maximum level 100%



Error indication by the current output: hold last value



Damping: 60 sec
