Do the 21X dataloggers have a built-in security code that might be activated under certain conditions when upgrading the program?
There is no built-in security code in the 21X. A security code can be set in one of two ways in the 21X:
- Enter a security code using *C and a four-digit number.
- Enter a security code in Edlog. Under Options, enter a four-digit security code into the program.
For more information on security, refer to Page 1-6 of the 21X Operator's Manual.
