Maintenance 
There are no user serviceable parts inside your blackbox, except the mains 
power fuse. If you experience any problems with the equipment, then please 
contact Pulsar Process Measurement for advice. 
Important Information 
Please note that the on-board Lithium battery, mounted to the 
processor PCB, is not user serviceable. 
 
 
To clean the equipment, wipe with a damp cloth. Do not use any solvents on 
the enclosure or transducer. 
Important Information 
The unique DATEM software comes into operation as soon as 
power is applied, and is designed to monitor a moving level or 
target with the transducer in a fixed position. 
If, after any period of use, it should become necessary to move the 
transducer, for any reason, from its original operating position, 
switch off the blackbox, before proceeding, to prevent any 
undesirable updates to the DATEM trace. If after moving the 
transducer the reading is not as expected, please refer to Chapter 6 
Troubleshooting.
