If the entered true value of the calibration signal does not fit within the range of
any calibration point, TC305/TC303 flashes the error message
BAD
VALUE
Enter a new value so, that it fits within the limits of one of the points in the table
above.
If the measured value differs too much from the entered value, TC305/TC303 only
flashes the error message:
CAL
ERROR
without altering the calibration. Check that the connected signal is correct and try
again.
The calculated calibration factors are now stored temporarily only. If you want to
save them permanently, press the key
q
STO and to the prompt
ENT=
SAVE
press the key
q
ENT . Now TC305/TC303 saves the new calibration factors to the
EEPROM memory and returns to the basic measure/generate operation. Pressing
any other key than
q
ENT causes return to the calibration mode.
If you want to exit the calibration mode without saving anything, switch
TC305/TC303 off.
