Interlock Function

Interlock Function
The interlock function is designed to prevent electrical shock when a user touches
the measurement terminals. If the interlock terminal is open, maximum output is
limited to 42 V.
To perform high voltage measurement greater than 42 V, connect the interlock
terminal to an interlock circuit of a test fixture or a shielding box. The interlock
circuit must have one LED and two mechanical switches that are connected together
and placed near the shielding box opening doors. For details on installing the
interlock circuit, see "Installing the Interlock Circuit" on page
The interlock function works as shown below.
When the interlock terminal is open, maximum output is limited to 42 V.
•
• When the interlock terminal is shorted, source channel can apply its maximum
output value.
• When the interlock terminal is opened in a high voltage condition greater than
42 V, the output voltage is immediately set to 0 V and the output switch is set
to off.
Open the interlock terminal so that the channel cannot apply dangerous
voltage when the source/measure terminal is touchable or opened.
Ouvrir la borne de verrouillage afin que le délivreur de tension ne puisse pas
appliquer de tension dangereuse lorsque la borne source/de mesure est à portée
de main ou ouverte.
