Introduction
Specifications
When one or more WGFMU modules are installed in the B1500A mainframe,
the following table applies. Multiply the values given below by the number of
installed modules of that type and add the products together. The sum of the
products must be less than or equal to 59 for the configuration to be permissible.
• Maximum voltage between common and ground
≤ ± 42 V
• Ground unit (GNDU)
The GNDU is furnished standard with the mainframe.
• Output voltage: 0 V ± 100 μV
• Maximum sink current: ± 4.2 A
• Output terminal/connection: Triaxial connector, Kelvin (remote sensing)
• Load capacitance: 1 μF
