Ametek MX45-3Pi - Table 6-1: Calibration Load Values

User Manual – Rev BE AMETEK Programmable Power
MX Series 210
measurement calibration coefficients are used on both voltage ranges (if
available).
Suggested load values are shown for either voltage range in case the MX
configuration used only has a single voltage range. (MX45-N-150 or MX45-N-
300).
