Ground level
⇒ The PersonalScope 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. The enclosure is UL 94V0 listed
⇒ 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 ( e.g. type PROBE60S) when measuring voltages exceeding 30V.

OPERATION
Switching from one readout to another
The Personal Scope offers many voltage measuring possibilities.
Press the “readout” key repeatedly to select one of four
possible readouts :
Peak voltage (Vp). The signal's peak-to-peak voltage
(difference between
highest and lowest
value) is displayed.
True RMS readout (Vr). The area of the AC wave is
calculated and converted to voltage. Please remember that
a correct readout invariably consists of at least one or two
visible periods (one can also use the auto-setup function).
dB measurement (dB). The measured signal is converted
to dBm (0dB=0.775V). Once more, the user should make
sure that at least one or two periods are displayed or select
the auto-setup function).
12
DC voltage measurement (V=). This function enables the
user to measure DC voltages (only for DC input coupling)
F
Useful tip for measuring DC voltages:
The readout can be set at zero (reference) for any
position on the screen by keeping the AC/DC key
pressed down. Always use the "run" trigger mode
for DC voltage measurement.
NOTE: If the signal goes off-screen or when the dBsignal is too small for
measurement, the
display will show.....

Determining the frequency of a signal requires the
measurement of a period. The easiest way to do this
would be by placing the vertical markers either on
two consecutive peaks or two identical slopes of a
signal.
Setting up the voltage per division
The user can enlarge or reduce the signal on the
screen vertically by adjusting the displayed voltage per
division. (V/div = voltage per division). The divisions can
be made visible through the Display key (see page 16).
Press the “t-V/div”key
Press the ⇑ or the ⇓ key to select the sensitivity : from
5mV to a maximum of 20V per division.
F 50mV to 200V with X10 probe selection
t-V/div
t-V/div Setting up the time base
Adjusting the time base will visualise more or
fewer periods of a signal (t/div = time per division). The
divisions can be visualised through the Display key (see
page 16).
Press the “t-V/div”key
Press the ⇐ the ⇒ key to set the time base between 20s
and 2µS per division.
ATTENTION : the positions 10µs, 4µs and 2µs only
operates correctly with periodic signals, for which the unit
will automatically select the ‘normal’ trigger mode. The
16
screen will be adjusted once the trigger level is reached.
NOTE: Use the minimum time base (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.
Moving the signal in Y-position
Press the “Y-pos”key
Press the ⇑ key or the ⇓ key in order to move the signal
in the direction of the arrows. Prolonged pressing will make
the Y- position change faster. A small dot in the left-hand
corner of the screen will indicate the direction in which the
signal has moved. In this manner, the user will know in
which direction the signal was going when it went offscreen.

The ⇐ (trigger mode) key enables the user to select the
appropriate triggering method, the ⇒ (slope) key is used to
select the trigger slope (see below).
trig
Press the ⇐ key repeatedly to choose between :
“run” mode: The signal will always appear on the
screen, regardless of the level involved. This
position is used most frequently and should always
be used for measuring DC voltages in particular.
“norm” mode: The screen will be adjusted provided that the signal falls within the trigger level
(interruption in the vertical line on the left-hand
side of your screen). Use this mode when you want
to start displaying the signal when it reaches a
preset threshold value.
“once” mode: The screen is adjusted one single
time, viz. when the trigger level is reached. Use this
mode to detect e.g. a short, once-only voltage peak.
ATTENTION : in the positions 10µs, 4µs and 2µs the unit
will automatically select the ‘norm’ trigger mode. The
trigger level has to be reached for the screen to be adjusted.
OPERATION
F
Both the ⇑ and the ⇓ key remain active in order
to move the signal along the Y-axis, which enables
the user to programme a trigger reference
Repeatedly press the ⇒ key to choose between :
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.
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.
Trigger on rising slope
Trigger on falling slope
NOTE : There is a time difference of ±12µs between the
trigger point (the interruption in the vertical line on the
left-hand side of the screen) and the start of the actual display.
This is specifically true on higher frequencies.
