All measurement connections should be considered to be hazardous.
The maximum floating (common mode) voltage for a source-measure unit (SMU) is ±250 V.
Exceeding this level may cause damage to the instrument and create a shock hazard.
Using an external source to float a SMU could create a shock hazard in the test circuit. A
shock hazard exists whenever >42 V is present in the test circuit. Appropriately rated
PEAK
cables or insulators must be provided for all connections to prevent access to live parts.
When >42 V is present, the test circuit must be insulated for the voltage used or surrounded
by a metal safety shield that is connected to a known protective earth (safety ground) and
chassis ground (see Safety shield (on page 4-16)).
