Factory service function 

code

48 - Calibrate instrument

TLA calibration. Refer to the Calibration section for details.

66 - Reset parameters to factory 

settings

Entering code 66 restores all parameters to factory settings. The  

unit indicates the operation after the P button is pressed, by 

displaying “rSEt” in the lower display momentarily.

77 (twice in succession) -  

Reset TLA calibration to nominal 

values 

Caution: this operation erases the TLA calibration values and 

defaults the values to nominal settings. Reading errors of ±10%  

may result. Do not perform this operation unless the TLA has lost 

calibration. Loss of calibration is signaled by an “E-CL” error  

flag at power-up. To clear this flag, perform calibration procedure  

as noted in the Calibration section. Alternatively, “stepping” through 

one of the calibration procedures clears the error flag, but does 

NOT validate the calibration accuracy in any manner.
