2611B, 2612B, 2614B, 2634B, 2635B, 2636B voltage measurement accuracy limits
Adjustment
The information in this section is intended for qualified service personnel only, as described
by the types of product users in the Safety precautions pages, provided at the beginning of
this document. Do not attempt these procedures unless you are qualified to do so.
Some of these procedures may expose you to hazardous voltages, that if contacted, could
cause personal injury or death. Use appropriate safety precautions when working with
hazardous voltages.
Use the procedures in this section to calibrate the 2600B.
These procedures require accurate test equipment to measure precise dc voltages and currents.
Product specifications are subject to change. Listed uncertainties and test limits are provided only as
an example. Always verify values against actual product specifications.
Environmental conditions
Temperature and relative humidity
Conduct the adjustment procedures at an ambient temperature of 18 °C to 28 °C, with relative
humidity of less than 70 percent (unless otherwise noted).
Product specifications that are listed as 18 °C to 28 °C assume adjustment has been done at 23 °C.
If the 2600B is adjusted at a different temperature, the specifications apply to ±5 °C of that
temperature.
Line power
The 2600B requires a line voltage of 100 V to 240 V at a line frequency of 50 Hz or 60 Hz. The
instrument must be adjusted within this range.
