Adjustment Procedures 3
Keysight 3458A Calibration Manual 37
Required Equipment
You will need the following equipment to perform the adjustments:
– A low-thermal 4-terminal short for the offset adjustments (this is typically a
bent piece of copper wire as shown in Figure 3-1 on page 39).
– 10 VDC Voltage Standard--Fluke 732A or equivalent (for the DC Gain
Adjustment).
– 10 kW Resistance Standard--Fluke 742-10 K or equivalent (for the Resistance
and DC Current Adjustment).
– AC Source-Keysight 3325A Synthesizer/Function Generator or equivalent (for
the AC adjustment).
The resultant accuracy of the multimeter depends on the accuracy of the
equipment used, the thermal characteristics of the short. and the type of cabling
used. We recommend high impedance, low dielectric absorption cables for all
connections.
