CONTROLS, CONNECTORS AND INDICATORS
Fig. 2. Vertical controls, connectors, and indicators.
VERTICAL
1. CH 1 and CH 2 VOL TS/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. VOL TS/DIV Readout-Consists of two small lamps
for each channel , located beneath the skirt of each
VOL TS /OIV 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
VOL TS/ OIV switch, and extends the maximum vertical
deflection to at least 25 volts per division (10 volt position).
4. UNCAL Lamp-Indicates when the VAR
VOL TS/ OIV control is out of the calibrated detent and the
vertical deflection factor is uncalibrated .
