11.2 ERROR CODES
11.2.1 INTRODUCTION
The Error Codes fall into two main categories:
a. Those which explain why the instrument has stopped; some of these are warnings
rather than errors.
b. Those which explain why the instrument will not respond to a new command.
Some of the code numbers appear only briefly in the Display, accompanied by a
warning "beep". However, they can always be recalled as described under STATUS, µP,
1st page.
If a Code Number appears in the Display, but is not in the following list, it is intended for
Service Engineer's use only.
11.2.2 ERROR CODES: SUMMARY
The Error Codes are assigned in groups as follows:
Group 0 = Errors Pertaining to Command Structure
01 Unknown command
02 Argument mismatch
03 Argument out of range
04 Floating point format error
05 Illegal request for value
Group 1 = Programming Errors
11 Illegal edit command
12 Command cannot be learnt
13 Program does not exist
14 Recursion attempted
15 Attempt to edit while program is running
16 Program Check Sum error
17 Program Exists
18 Copy complete
Group 2 = Parametric Interaction Errors
21 The combination of Frequency and Harmonic is > 65kHz
22 The combination of some or all of Generator Amplitude, Bias, Waveform and
Modulation gives > 15V peak (21V for 1250N)
23 The combination of some or all of auxiliary Generator Amplitude, Bias,
Waveform and Modulation gives > 15V peak (21V for 1250N)
24 The combination of Frequency, Harmonic and Integration Time is out of range
25 Plotter MINIMUM> MAXIMUM
26 Order Analysis incompatibility
Group 3 = Generator Warnings and Errors
30 Generator stopped by command
31 Generator overload or Generator power failure
32 (Spare code)
33 Auxiliary Generator overload or Auxiliary Generator power fail
34 Modulation Channel 1 overload
35 Modulation Channel 2 overload
