ZGS-12216-1 

Load Cell Calibration  

 

Install a hoist and make all electrical and mechanical attachments. 
 
Configure the load cell readout according to section 4 of the DP25B-S User manual. 
 
Input type is 100 mV 
Set the decimal point to the default 0000 
Dip switch setting is  
12345678 
COCOOCOO 
 
Set Rd.CF  R.2=1 
 
If a 600 lbs load is available Scale the meter according to section 4.3.1. 
 
With the UUT mounted on the hanging hoist mount with no load on it and with the 
mount attached to the load cells, store the IN 1 value as the unscaled display reading 
shown and set the RD 1 value to zero. 
 
Then lower the UUT hook and attach the load and raise the 600 lbs weight until the 
weight is off the ground.  
 
Store the IN 2 reading and input the Rd 2 value as 600 lbs. 
 
 
Note: This procedure can be performed with a lower or a higher load, and the Rd 2 
value is then adjusted to the exact weight used. Using a value of 600 lbs insures 
maximum accuracy, but is not essential.
