What are the accuracies (measurement uncertainties) of 497, 493, and 494 Conditioners?

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”
