Can I configure the 34970A for 4-wire resistance, 4-ohms, and/or 4-wire scan?
Can I configure the 34970A for 4-wire resistance, 4-ohms, and/or 4-wire scan?
A standard 34970A (contains internal DMM) can be configured for 4-wire resistance measurements and/or 4-wire RTD temperature measurements using a 34901A or 34902A module card. For 4-wire resistance or 4-wire RTD measurements, the instrument automatically pairs channel n with channel n+10 (34901A) or n+8 (34902A) to provide the source and sense connections.For a 34970A with option 001 or with a standard 34970A with the internal DMM disabled, you can configure the list of channels for 4-wire external scanning. When using 4-wire scan with an external instrument, the 34970A automatically pairs channel n with channel n+10 (34901A) or n+8 (34902A) to provide the source and sense connections.
