3. + and - Inputs for applying external dc power
source {+9 to +32 volts! {Figure 3).
4. DMM INPUT-Connector to apply external voltages
or resistance to be measured to the digital multimeter
(Figure 3).
5. Ground Connector-Connector for common ground
connection from the power source or associated instruments
or devices under test {Figure 3).
6. CHI (X) INPUT-BNC connector to apply an external
signal to the input of the CHI vertical system, or X-axis
deflection {horizontal) in the X-Y mode of operation
(Figure 4). The maximum safe ac or dc voltage coupled to
the CHI (CH2 or EXT TRIG INPUT, if applicable) input
connector should not exceed 250 V (dc + peak ac).
7. CH2 (Y) INPUT-BNCconnector to apply an external
signal to the CH2 vertical system, or Y-axis (vertical) in the
X-Y operation mode (Figure 4).
8. EXT TRIG INPUT-BNC connector to apply an ex
ternal trigger input signal (Figure 4).
9. Ac Line Cord-Connects the instrument to an ac
power source (Figure 3). The cord may be conveniently
stored by wrapping it around the feet on the rear cover
(Figure 4),
