POWER SUPPLY & LOAD RESISTANCE

Ashcroft’s TruAccuracy™ specification is exclusively based on terminal

point methodology instead of statistically derived schemes like

‘best fit straight line’.

TruAccuracy™ means the Ashcroft S1 has standard span accuracy of

±1.00% with option to purchase as ±0.50% out of the box. Zero and

span setting errors are already included in the standard ±1.00% or

optional ±0.50% of span accuracy spec

The S1 is ready to be installed with no additional calibration

adjustments required.

A unit from another manufacturer advertised as ±0.25% best fit

straight line may actually be a ±1.25% to ±2.25% device. Using best

fit straight line method, the accuracy spec does not include zero and

span setting errors, which can be as much as ±1.00% each.
