Instruction Sheet
Thermo Scientific Orion Conductivity Calibration Kit
The conductivity calibration kit contains six resistors that simulate standard conductance values on a meter. The resistors may be used to verify proper meter function by comparing the meter reading to the conductance of the resistor. Note: The conductivity calibration kit verifies proper meter function only. After the meter function is verified, the conductivity cell must be calibrated. Calibrate the cell constant of the conductivity cell according to the meter and cell user guides.
Resistor Specifications
Each resistor is labeled alphabetically. The actual resistance and conductance values are printed on each resistor. The nominal resistance and conductance values are listed on the label of the calibration kit box for reference.

Verification of Meter Accuracy
Remove the conductivity cell and temperature probe from the meter. Perform a manual calibration on the meter and set the cell constant to 1.000 cm-1. Set the temperature value to 25.0 C and turn the temperature compensation off. Refer to the appropriate meter user guide for directions on cell constant and temperature adjustment. Attach a resistor to the meter by aligning the tabs on the resistor and meter. Push the resistor in until firmly in place. If the alignment is incorrect, the resistor and/or meter input can be damaged. When the meter indicates a stable conductivity value, compare the displayed value to the actual conductance of the resistor. The displayed conductivity value for each resistor should fall within the accuracy specification of the meter plus 0.5% of the actual resistor conductance. Since the resistor kits are made to test the accuracy of the meter, it is important that each displayed resistor value falls within the meter accuracy specification. If the displayed reading is not in the correct range, contact Technical Support. Within the United States call 1.800.225.1480 and outside the United States call 978.232.6000 or fax 978.232.6031. In Europe, the Middle East and Africa, contact your local authorized dealer.
