VPS10 Panel ScopeTM
SAFETY AND WARNINGS
The Panel Scope is ideally suited for measurements of
category II installations with pollution degree 1 and using a
maximum of 600V, in accordance with the IEC1010-1 norm.
Consequently, all measurements should be avoided in case
of polluted or very humid air. One should also refrain from
measuring conductors or installations that use voltages that
exceed 600Vrms above ground level. CAT II indicates
conformity for measurements of domestic installations.
The maximum input voltage for the connections of the unit
stands at 100Vp (AC+DC)
Do NOT open the enclosure while performing measurements.
Remove all test leads before opening the enclosure in order
to avoid electrical shock.
Use a measuring probe with an insulated connector when
measuring voltages exceeding 30V. (PROBE60S).
VPS10 Panel ScopeTM
POWER SUPPLY
The VPS10 Panel Scope can be powered by means of an adapter, transformator or a battery.
Attention:
Use a non-regulated or regulated adapter of 9VDC that supplies a min. of 300mA.
For car use, mount a 315mA fuse and a 22ohm (1W) resisitor in series with each other and with the power supply.
To prevent damage to the panel scope, connect the input to the sound source through a 1/1 transformer.
Another possibility is to pick up the sound signal by means of a microphone that is connected to the input of the panel scope.

and 0.2µs per division.
Press the ‘MODE’ button repeatedly until the ‘t/div’ settings
appear.
Press the ‘up’ or ‘down’ cursor keys to increase or decrease the
timebase (time/div).
Note:
• Changing the timebase or sensitivity switches the
autorange mode immediately off. (Fig 8.0)
• At higher timebase (2us and faster) the scope uses
oversampling mode, only repetitive signals are correctly
displayed.
• Use the minimum time base (0.2 microsec) as a starting
point when measuring a signal and select longer time
bases until the signal is displayed properly. Otherwise the
display may not correctly reflect the signal under
measurement due to aliasing.
• Keeping the 'Up' or 'Down' button pressed for a long
time enables autorange.
• When autorange is enabled (time/div and V/div are
highlighted), it will be disabled as soon as the 'Up' of 'Down'
button is used.

PROBE SETUP
Press the ‘MODE’ button repeatedly until the ‘INPUT’ settings
appear.
Press then the 'Down' button, it allows you to determine the
measuring probe setting as x1 or x10.
Setting up a X10 measuring probe
When used in the X10 position, a measuring probe should
always be calibrated to the measuring instrument being used,
in this case the Panel Scope. (Fig. 10)
• Set the probe input to X10
• Set the voltage per division to 1V
• Set the time per division to 0.1ms
• Select AC for the input.
Use the probe to perform measurements at the preselected
point on the front panel. Adjust the trimmer of the measuring
probe in order to obtain a square wave signal with a top that is
as flat as possible. (Fig. 11)
Notes:
• An ‘x10’ symbol is displayed if this mode has been selected.
• X10 measuring probes should be calibrated!
Fig 11
• IMPORTANT: Set the measuring probe in the x10 position for
measuring high voltages (>100Vp+dc)

Press the ‘MODE’ button repeatedly until the
‘INPUT’ settings appear.
A short activation of the 'Up' button will switch
between ac (2) or dc (1) input coupling.
When measuring the ”ripple” of a DC
voltage : put the input on AC to limit the
measurement to the AC component of the
signal.
Note:
• At time bases of 1s/div and slower, the
input coupling is DC-only.
SET THE INPUT REFERENCE
Keeping the 'Up' button pressed for a longer
time will internally connect the input to ground
and will keep the current readout as zero
reference for dc measurements.

• Operating the 'Up' button will move the screen to the right
• Operating the 'Down' button will move the screen to the left
Prolonged pressing will make the X-position change faster.
Notes:
A total of 256 samples are stored in memory, but the Xsize of the screen is limited. By shifting the X-direction
you can display all stored samples.
Y - position mode :
Press the ‘MODE’ button repeatedly until the ‘Y-pos’
setting appear.
• Operating the 'Up' button will move the displayed signal
upwards.
• Operating the 'Down' button will move the displayed
signal downwards
Prolonged pressing will make the Y- position change faster. A
small dot (3) in the left-hand corner of the screen will indicate
the direction in which the signal has moved (Y pos).
In this manner, the user will know in which direction the
signal was going when it went off-screen. (Fig 15).

Trigger setup
VPS10 Panel ScopeTM
THE TRIGGER SETUP
Press the ‘MODE’ button repeatedly until the ‘trigger’ setting
appear.
• Use the ‘UP’ cursorkey to change the trigger-mode (norm,
run or roll).
Trigger modes :
”norm”= Normal trigger: A triggering (or manual trigger) must
occur before the sample memory is filled. Use this mode when
you want to start displaying the signal when it reaches a preset
threshold value. (Fig 16)
“run”= Auto-trigger mode, the scope automatically triggers if
no triggering occurs for a fixed period of time. This position is
used most frequently and should always be used for measuring
DC voltages in particular. (Fig 17)
“roll”= Roll-mode is available for timebases of 1s/div or slower.
Sampling is continuous and the screen starts rolling as soon as it is
full. Use this position for “recording” slow moving dc signals. (Fig 18)
Notes:
• At time base of 1s/div and slower, the input coupling is DC-only
• Normal triggering is the only triggermode for timebases of 2µs/div
or faster because of the oversampling method.
16
Trigger slope
Press the ‘DOWN’ cursorkey to set triggering at the rising or
falling edge of the input signal.
Triggering on the rising slope of the signal :
The screen will only display the signal when a positive slope is
"detected", viz. the signal has to rise in vertical direction in
order to trigger. (Fig 14)
Triggering on the falling slope of the signal:
The screen will only display the signal when a negative slope is
"detected", viz. the signal has to drop in vertical direction in
order to trigger. (Fig 15)
Notes:
Between triggering and the first sample-aquisition there is a
fixed hardware-determined delay. Because of this delay, the
sampled signal can show a different slope at fast timebases.
