4.11 How to Use 25Ω Calibration Checker
The calibration checker is good for both the 3640 and 4610. It has a
resistance of 25Ω. The procedure to use the calibration checker is as
follows:
• LoosentheX,XV(4610only),YandZterminals.
• InserttheresistorasshowninFigure23.
• TightendowntheterminalsX,XV(4610only),YandZ.
• Pushdownthe“PresstoMeasure”button.
• Comparethereading onthe displayto the measurementrange
providedonthelabel.
NOTE: For alignment purposes of the test resistor, it is recommended that the
shorting links remain connected between X and XV for the Model 4610, and
Y and Z for the Models 3640 and 4610.
Forexample,ifacheckwasperformedontheModel4610or3640,the
displayshouldshowareadingbetween24.15Ω and 25.85Ω.Ifso(asin
Figure23),theinstrumentisingoodworkingcondition.
