Do not apply excessive voltages between insulated signal terminals. You
could be suffered from electric shocks, if excessive voltages are applied
between these terminals leading to dielectric breakdown.
You could be suffered from electric shocks when you measure high voltage
circuit signals. Use accessory coaxial cables of the insulation type by all
means, so that you cannot directly touch metallic portions of the BNC
connectors at the analyzer input terminals.
