SAFETY INFORMATION

SAFETY INFORMATION
The Panel Scope is ideally suited for measurements of category II installations.
Consequently, all measurements should be avoided in case of polluted or very humid air. The maximum input
voltage for the oscilloscope unit stands at 100Vp (AC+DC)
All in– and outputs are electrically separated. Do not open the enclosure.
Use a measuring probe with an insulated connector when measuring voltages exceeding 30V. (PROBE60S).
Check the probe specifications before measuring high voltages!

MAINTENANCE

MAINTENANCE
• No user serviceable parts inside. Remove power cord, to access the AC power fuse.
• Avoiding fire risks : respect the specified voltage and current ratings when replacing the fuse
• Check the mains cord for damage before connecting to the AC power
• Do not apply abrasives or solvents. Use a damp cloth and mild detergent for cleaning purposes.

DURING USE

DURING USE
• Never exceed the limit value for protection. This limit value is listed in the specifications.
• Do not touch unused terminals when the unit is linked to a circuit which is being tested.
• When carrying out measurements on a TV set or switching power circuits, always remember that the meter may
be damaged by any high amplitude voltage pulses at test points.
• Always be careful when working with voltages above 60Vdc or 30Vac rms. Keep your fingers behind the probe
barriers at all times during measurement.

You can:
• Change the user interface language (only for generator!)
• Adjust the display contrast or reverse the display (black with white dots)
• Change the way the frequency is changed if you keep the up/down button
pressed ( Log. will make the frequency change faster).
• Start or Stop the DEMO mode
(useful if connected to the oscilloscope, for demonstration or testing)
• Long press the menu button to leave the menu and store the settings
