VERTICAL
1. CH 1 and CH 2 VOLTS/DIV—Selects the vertical
deflection factor in a 1-2-5 sequence (VAR control must be
in the calibrated detent for the indicated deflection factor).
2. VOLTS/DIV Readout—Consists of two small lamps
for each channel, located beneath the skirt of each
VOLTS/DIV knob. One or the other lamp will light up to
indicate the correct deflection factor when a probe with a
scale-switching connector is used. A probe without this
connector lights the X1 lamp.
3. VAR--Provides continuously variable uncalibrated
deflection factors between the calibrated settings of the
VOLTS/DIV switch, and extends the maximum vertical
deflection to at least 25 volts per division (10 volt position).
4. UNCAL Lamp—indicates when the VAR
VOLTS/DIV control is out of the calibrated detent and the
vertical deflection factor is uncalibrated.
