(5) CAL
The terminal provides a reference signal of 0.5Vp-p at 1kHz for probe
adjustment.
(6) Ground Socket—Banana Socket galvanically connected to safety earth
This socket can be used a reference potential connection for DC and low
frequency signal measurement purpose.
(7) TEXT/ILLUM—Control knob with a double function.
The pushbutton is for selecting the text readout intensity function or scale
illumination function, and indicates the letter “TEXT” or “ILLUM” in the

△ V: Two horizontal cursors appear. The voltage between the two cursors
is calculated according to the setting of VOLTS/DIV, and displayed
with △V on the upper side of the CRT.
△ T: Two vertical cursors appear. The time between the two cursors is
calculated according to the setting of TIME/DIV, and displayed with
△ T on the upper side of the CRT.
1/△T: Two vertical cursors appear. The reciprocal of the time (frequency)
between the two cursors is calculated with 1/△T on the upper side of
the CRT.
C1—C2—TRK Pushbutton
The cursor 1, cursor 2 and tracking can be selected by this button. Pressing the
pushbutton to select the cursors in sequence as follows:
C1: Moves the cursor 1 on the CRT(▼ or
symbol is displayed)
C2: Moves the cursor 2 on the CRT(▼ or symbol is displayed)
TRK: Simultaneously moves the cursor 1 and cursor 2 with the interval
between the two cursors unchanged (both symbol are displayed at the
two cursors.)
(9) VARIABLE—
Set the cursor position, TEXT/ILLUM, etc. by turning or pressing the
VARIABLE knob.
In the cursor mode, pressing the VARIABLE control knob to select the cursor
position between FINE and COARSE adjustment. When select FINE
adjustment by turning the VARIABLE, the cursor lines will move slowly. If
select COARSE adjustment, he cursor will move fast.
In TEXT/ILLUM mode, this control knob can be used to set the text intensity
or illumination. Please refer to TXT/ILLUM(7) for details.
