12.1.6 MENU CHANGES ACTIVATING THE HEADING AND REFORMAT
FUNCTIONS
HEADING and REFORMAT may be initiated by changes to any of the following menus:
a. Any FUNCTION menu
b. The [DATA OUTPUT] menu
c. The [DISPLAY], SOURCE and CO-ORDS menus
d. The [ANALYZER COMMON], ORDER menu
Note: Making any of these changes, with either HEADING or REFORMAT 'on', causes
a result to be sent to the File if it is also 'on'. This could happen, for example, when
switching on the RS423 port in order to print out the filed results of a Sweep
measurement.
To prevent this inadvertent filing of results, which could be confusing or cause
overwriting and loss of data, it is advisable to switch off the File once the required
results have been filed.
12.1.7 CHANNEL & RANGE COLUMN CONVENTIONS
In the 'Channel & Range' column (See Fig. 12.1), the first two pairs of digits separated
by an oblique give the SOURCE channel(s), and the bracketed figures prefixed by "R"
and separated by an oblique give the Analyzer RANGE(s) operative for that
measurement.
The ranges are coded as follows:
Code Range
1 30 mV
2 300 mV
3 3 V
4 30 V
5 300 V
So, for example, the following entries have the meanings shown:
CHANNEL MEANING
& RANGE
ENTRY SOURCE RANGE
02/01(R1/3) Ch 2/Ch 1 Ch 2:30 mV
Ch 1:3 V
01/00(R3/0) Ch1 only 3V
