RE: HP 3468 voltmeter with HP-IL
Hi Ignacio,
The thing is, you might have some equipment but it doesn't have the required accuracy. The DC Voltage Standard (power supply), for example, needs to have an accuracy of +/- 0.005% or better. The rule of thumb is the equipment needed should be at least 10 times as accurate as the equipment your're calibrating. Dave |
