Locate the instrument on a clean workbench in an area where the temperature is between 18 degrees Celsius and 29 degrees Celsius (65 degrees Fahrenheit and 85 degrees Fahrenheit) and does not vary more than plus or minus 3 degrees Celsius, or 5 degrees Fahrenheit. Open the case and raise the right panel until completely vertical and locked in place. If an AC power is available, connect the power cord and turn the instrument on. If the internal battery power is used, ensure that the batteries are charged sufficiently to perform the desired number of tests. Low battery power is indicated when the power lamp does not illuminate. Connect the instrument to an AC power source for at least 16 hours (full charge) prior to use. Approximately 25 tests can then be performed. If the battery in a Mark 10 is not charged sufficiently to run a test, an ERR-06 will be displayed, indicating that the battery must be recharged. Mark 5 Deluxe and Mark 10 instruments are turned on by depressing the switch (push button) marked ON. The ON power indicator light will alternately pulse on and off when the instrument is connected to an AC power source and will stay on continuously when operated by the battery pack. Flickering of the power indicator light, during any portion of a test sequence being performed using battery power, indicates that recharging is necessary. Have ready a supply of syringes, vials, Alumicel coalescers, syringe plugs, and pipet tips, as well as a clean container with distilled water. All of the items are furnished in the 6 pack provided with the instrument. In addition, have the pipet readily available. Syringe drive travel times during the coalescing test period were initially calibrated at the factory for each mode of operation and have a significant bearing on the final test results. Both the Mark 5 Deluxe and Mark 10 instruments have self-check circuitry to detect out-of-tolerance syringe drive travel times. Syringe drive travel times exceeding the upper limit will cause the final results to measure high; conversely, travel times below the lower limit will cause the final results to measure low. The alert indicator lamp (marked SYR) illuminates and depending on the degree (more than 3 seconds) of the out-of-tolerance condition, three short (1 second) tones will also sound. An occasional out-of-tolerance alert may be experienced due to some intermittent condition, which probably will not be indicative of instrument failure. However, repeated alerts are cause for returning the instrument to the factory for adjustment. During a test, the error alert indicator will illuminate, and ERR-03 will be displayed indicating an out-of-tolerance syringe travel time. Error alerts ERR-01 and ERR-02 will be displayed if the syringe stalls while traveling up or down, respectively.
