)

Fig. 19: Take the gravity weight into account and shorten the cable respectively

5.  Shift the gravity weight again flush to the cable and fix it with the 

two pins.

6.  Mount the probe into the vessel. Make sure that the probe is 

uncovered.

2  Control lamp

7.  Keep the measuring range selection switch (1) pushed until the 

control lamp (2) flashes green.

8.  Hence the probe is compensated to the modified length.
9.  Carry out the adjustment again. See chapter " 

Set-up, adjustment 

elements

". 

7.5  How to proceed if a repair is necessary

You can find an instrument return form as well as detailed information

this you help us carry out the repair quickly and without having to call 

back for needed information.
Proceed as follows in case of repair:

• 

Print and fill out one form per instrument

• 

Clean the instrument and pack it damage-proof
