4 - 74HOW TO USE THE INSTRUMENT

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 Δ 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.
