Meter Checkout (pH) Meter Checkout (Conductivity)Note: Requires the conductivity calibration resistor kit for Orion Star A series conductivity meters, Cat. No. 1010001,which must be purchased separately.resistors may be used to verify proper meter function by comparing the meter reading to the conductance of theresistor. The conductivity calibration kit verifies proper meter function only. After the meter function is verified, theconductivity cell must be calibrated. Calibrate the cell constant of the conductivity cell according to the meter and cell1. Remove the conductivity cell and all other electrodes from the meter. . can be damaged.
