SETUP TEXT LABEL
In the setup menu each stored setups can be given a label of user defined text.
This is done in the submenu TEXT of the SETUP menu. The cursor controls are
used for editing text. The TRACK control is used as "cursor", The control is used
for selecting the character.
SETUP RECALL A SEQUENCE
You can create a sequence of setups by storing setups to successive locations
(e.g. s1, s2, s3) and clearing the next location (e.g. s4). The AUTOSET key then
can be programmed to step through this sequence. This is very useful for semi
automated manufacturing. To program the AUTOSET to be used for STEP-TO-
NEXT-SETUP-IN-THE-SEQUENCE select the UTILITY >> AUTOSET submenu
and select setups.
AUTOCAL
The AUTOCAL function is used for fine adjustment of the oscilloscope’s input,
trigger, and timebase circuitry. This allows you to achieve the high accuracies
specified for this instrument, even under extreme environmental conditions like
very high or very low temperatures.
When the oscilloscope is always kept under the same environmental conditions
(e.g. in a workshop or lab.), it is sufficient to perform this AUTOCAL once every
month.
It is recommended that you perform an AUTOCAL after the instrument has
warmed up.
To perform an AUTOCAL :
- Press the CAL key for at least 2 seconds.
The calibration is fully automatic and takes about 4 minutes.
For purposes of full traceability, an official calibration in a fully equipped and
traceable calibration laboratory should be done once a year or after every 2000
hours of use.
