The product’s input power capacity is fixed as shown below to prevent electric shock and/or fire.
Please DO NOT use voltage higher than that prescribed below.
Probe Attenuation Maximum Input Voltage Input Impedance
1:1 42Vpk, AC 30Vrms, DC 60V 1MΩ
10:1 420Vpk, AC 300Vrms, DC 600V 10MΩ
100:1 4.2KVpk, AC 3KVrms, DC 6KV 100MΩ
1000:1 42KVpk, AC 30KVrms, DC 60KV 1GΩ
(Warning) Be sure to check the probe attenuation before measuring the voltage. The voltage that is
