Connect the probe to the connector on the EMCEE digital conductivity meter and depress the Measure switch, M, with the probe out of the fuel sample. Zero reading should be 000, plus or minus 001, in approximately three seconds. If the instrument does not meet the specification, remove the probe and depress Measure switch, M. If the instrument meets the specification without the probe attached, the probe should be thoroughly rinsed with isopropyl alcohol and allowed to air dry before retesting for zero. If the instrument does not meet the specification without the probe attached, then the adjustment procedure of A2.4 of the written standard should be performed. Note the calibration number stamped on the probe. Depress the Calibration switch, C, with the probe out of the fuel sample. The reading should be 10 times the number stamped on the probe, plus or minus 005, after approximately three seconds. For example, probe number equals 40, meter reading must be 400 plus or minus 005, 395 to 405. If instrument does not meet specification, proceed to A2.5 of the written standard. Zero adjustment is performed without the probe attached and the Measure switch, M, depressed. Insert a screwdriver in the hole marked zero, and adjust the control until the display reads 000, plus or minus 001. Calibration is performed without the probe attached and with the Calibration switch depressed. Insert a screwdriver in the hole marked Calibrate, and adjust to within plus or minus 002 of 10 times the number stamped on the probe. Do not attempt to adjust the meter using the plugged hole between the Zero and the Calibrate holes.
