Note:
The settings of some parameters are dependent on 
others and if a confl ict is encountered error messages 
will appear on the screen and/ or the instrument will 
beep. Some are as follows:
With an 8 mm (two digit) probe code in place, you can-
not select a frequency of 60 kHz (only useable with 
12.7 mm probe). If it is attempted the instrument will 
beep and not carry out the change. It is then neces-
sary to move to the PROBE parameter and recall 
the correct four digit code number appropriate to the 
12.7 mm probe to be used.
When the set probe routine is being carried out, if the 
wrong probe code is in place i.e. two digit number is 
present (8 mm probe) when trying to set a 12.7 mm 
probe which should have a four digit code number or 
vice-versa. The display will show an error (see Fig-
ure below), and will prompt a press of the SET button
