The upper row of the display will indicate the operational status of the security access option (on or
off). You can change the operational status of this option using either the S or T keys. Once you
have set the desired status, press the key to accept it.
If you selected to turn on the security access code, you will need to input an access code to be used
for entering calibration and for entering the configuration mode. The security key will be
highlighted on the display and the word “S-C” will be shown on the lower row of the display while
the current access code for entering calibration is shown on the upper row of the display (C followed
by 4 numbers).
If you wish to change the code you may change each of the four numbers one at a time. Use either
the S or T keys to select the first number in the code then press the key to move to the next
number. Follow this process through the four numbers in the access code. When you are satisfied
with your selection, press the key to accept the number. The access code will change from the
calibration access code to the configuration (user setup) access code (S followed by 4 numbers).
Select the access code for the configuration/setup mode as you did with the calibration mode.
