QUESTION
What are the accuracies (measurement uncertainties) of 497, 493, and 494 Conditioners?
ANSWER
497
Considering the age of 497 conditioner product line, definitive accuracy specifications do not exist.
However, based upon our experience calibrating various 497 conditioners, the estimated accuracy specification is:
497 DC Conditioner: ±0.25% of Reading + 0.01% of Range
407
Considering the age of 407 conditioner product line, definitive accuracy specifications do not exist.
However, based upon our experience calibrating a few 407 conditioners, the estimated accuracy specification is:
407 DC Conditioner Gain Accuracy: ±0.25% of Reading + 0.01% of Range
407 DC Conditioner Analog Output: ±0.25% of Reading + 0.001 mV.
493
Similar to 407 and 497 hardware, definitive accuracy specifications for older 493 conditioners does not fully exist.
Based upon our experience calibrating 493 DC Conditioners, the estimated accuracy specification is:
493 DC Conditioner: ±0.25% of Reading + 0.001% of Range
494
MTS published accuracy specification for a 494 (DC-Mode) conditioners is:
494 DC Conditioner: ±0.1% of Reading + 0.001% of Range”
