(33)AUTOSET—
Pressing briefly the AUTOSET pushbutton to set the instrument to the
last time base mode of CH1, CH2 and DUAL.
At the same time, the attenuators VOLTS/DIV are automatically set at
a signal display height of approx. 3-6 div in mono channel mode or at
approx. 3 div height in DUAL mode for each channel.
The time range would change automatically and approx. 1.6 to 4
waveforms are displayed on the screen. For signal of 100Hz or in the
absence of a trigger, the time range is set to 5ms/div, and for the
signals of approx. 8MHz or more, it is set to 50ns/div. The time range
change automatically following the different incoming signal.
Proceed AUTOSET function to operate the instrument automatically
according to the following condition:
1. Set input coupling to AC.
2. Set internal triggering(CH1 or CH2).
3. Set deflection coefficients between 5V/div and 2mV/div calibrated
condition.
4. With main time base alternate and set off delay time base mode.
5. Automatic CH1 and CH2 horizontal position settings.
6. Trace and readout visible.
7. Set trigger level to zero, trigger mode to AUTO, and trigger
coupling to AC.

(34) MEMO- 9 —SAVE/RECALL
The instrument contains 10 non-volatile memories, which can be used
by the operator to save instrument setting and to recall them. It relates
to all controls which are electronically selected.
Press or pushbutton to select the memory location. The
readout then indicates the letter “MEN” followed by a cipher between
0 and 9. Each time the pushbutton is briefly pressed the memory
location cipher increases until the number 9 is reached.
The pushbutton is similar but decreases the memory location
cipher until the number 0 is reached. Pressing and holding SAVE for
approx. 3 seconds to write the instrument settings in the memory and
indicate the associated readout information of “SAVED”.
To recall a front panel setup, select a memory location as described
above. Recall the settings by pressing and holding the RECALL
pushbutton for approx. 3 seconds, the readout then indicates the
associated readout information of “RECALLED”.
(35)MEAS’MT FUNC-CURSOR—
Pressing and holding the pushbutton to set Cursor measurement mode
on, then press briefly the pushbutton, the seven measurement functions
listed below will be selected in the sequence. Pressing and holding the
pushbutton again to set the Cursor measurement mode off.
The seven Cursor measurement functions:
△V : Voltage difference measurement.
△V% : Voltage difference percentage measurement
(5div=100% reference)
△VdB : Voltage gain measurement.
(5div=0dB reference,△VdB=20 log (△V div/5div)).
