mA Trim 
P838 mA Low Trim 
When entering this parameter, you will see the following options displayed 
on the screen: 
Type in the value seen on the DMM and press enter 
again, and you should see 4mA on your DMM.  
‘Enter if measured mA = 4mA’ appears, if the 
reading is correct press enter to save the change. 
When looking back at the parameter you will only 
see the offset value entered. 
If the remote device you are connected to is not 
calibrated, and not showing the correct low or high 
value (reading), then you can trim it using the trim 
parameters.  
You can either type in the offset directly or use the 
arrow keys to move the output up and down until 
you get the expected result (reading) on the remote 
device that is connected. 
 
Example: 
Measured: When looking at P838 and the DMM is reading 4.32mA, you 
would type a value of 4.32 into the parameter and press enter.  The unit will 
then output a reading of 4mA. 
   
Important Notice 
To correctly trim the Ultra 4 mA, connect your DMM to the mA out 
terminals and screw down so the probes of the DMM are secure.
