1.0 PRODUCT DESCRIPTION The PT, LP and PU series of products are heavy duty portable and permanent platform type scales, they all use the same load cells, Indicator cables and base connectors ensuring conformity within the range. They are made from heavy gauge mild steel using a strong construction design to ensure maximum capacity readings are correct and accurate. 4 x Load cells are fitted and adjusted for exacting and matched output using an Off Centre Loading (OCL) adjustment PCB where necessary.

5.0 VIEW OF OCL ADJUSTING PCB To evaluate that the load cell signal output is correct you can make certain measurements. The load cell functions using a 5Vdc input and this can be checked by placing two individual probes from a multi meter between the (exc +) and (exc-) cables at the load cell output connection from the OCL PCB.
You should expect to see a positive voltage reading of between 0 and 2 milli volts when the load cell assembly is at no load, and when a downward force is applied to the load cell assembly the reading should increase. If with no load a reading of more than 2 milli volts is recorded then this suggests damage to a load cell may have occurred and a replacement load cell is required.
7.0 BASE TO INDICATOR CABLE CONNECTIONS All base to Indicator cables are 7 core and wired following the pin numbers as below.
