Remove the probe from CAL 2 Vpp terminal [1]. Set switch VERTICAL-MODE [39]
to CH2 position and repeat the process for CH2, each one with its own probe.
Now the oscilloscope is ready to be used.
4.3 OPERATION METHOD
4.3.1 Single-Channel Operation
Single trace and base time operation and internal triggering is the most basic
operating mode of the OD-514B, OD-515B & OD-545B. Select this mode when there is
only one signal to be observed, without the inconvenience of other traces on the CRT
screen. Due it is a two channel oscilloscope, any of these two channels can be selected.
CH1 is provided with and output terminal: use the CH1 output terminal on the rear panel to
measure signal frequency using a frequency counter while observing waveform. CH2 have
a switch that inverts polarity, although it adds flexibility, it has no use when operating in
single trace mode.
OD-514B, OD-515B and OD-545B are set for single channel operation as follows:
1. Set the following controls of the instrument as shown below. Observe the
selected triggering source (CH1 or CH2 SOURCE) corresponds to the selected
channel (CH1 or CH2 V MODE).
VERT MODE
TRIGGER MODE
SWP. UNCAL
2. Position trace near the centre of the screen by means of the
control [37] or
3. Connect the signal to be observed to the appropriate input terminal CH1 [12] or
CH2 [16] and adjust the appropriate VOLTS/DIV selector [10] or [14] so that
signal waveform is completely displayed on the screen.
WARNING
Do not apply signal higher than 400 V (DC + AC peak)
