Notes:

1) Where measurement conditions have not been specified precisely, the conditions used were an ambient temperature of +23 ℃ +73.4 ℉.
2) The red backlight of the pointer part lights up more brightly when the power is turned ON and when the sensitivity is adjusted.
3) When the power supply is switched on, the emission timing are automatically set for interference prevention.
4) The voltage withstandability and the insulation resistance values given in the above table are for the amplifier only.
5) The cable for amplifier connection is not supplied as an accessory. Make sure to use the optional quick-connection cable given below.
