• Before using the device the first time, verify that it operates normally to ensure that no damage occurred during storage or shipping. If you find any damage, contact your authorized Hioki distributor or reseller. This device is designed to measure voltages of 60 V or lower. Do not input voltages over 60 V or measure locations exceeding 60 V from the ground potential.
Page 9 Prevent the voltage potential difference of the entire system from exceeding 60 V DC. The measurement connector frame of the module is connected to the casing (metal) of the device as well as the protective ground terminal of the power inlet (conductive). HIOKI SW1001A961-04...

Page 152: Measuring Object Short Circuit Due To Relay Contact Welding
12.2 Measuring Object Short Circuit due to Relay Contact Welding The SW9001 and SW9002 multiplexer modules switch a measurement signal using a mechanical relay. The relay contact may weld when relay switching is repeated with a large current flowing (also when the measuring object or instrument to be connected is capacitive).
Page 153 Measuring Object Short Circuit due to Relay Contact Welding Module fuse rating The SW9001 and SW9002 are provided with a fuse (board mounted type) in HIGH and LOW for each channel input to prevent possible risks if a high current flows through the circuit due to relay contact welding.
