Media-Mate Plus Operation Manual 25-710-800-OSection Six – Validation and CalibrationPre-Heat Temperature CalibrationCalibration of the temperature control system is recommended every six months for 32°C and37°C set points. A Temperature Calibration Log is provided and may be copied for entry oftemperature calibration data.1. Place Calibrated Thermometer (p/n 65-233-401) in the 3/8 in. hole provided in the TankCover (hole located furthest from Heater Assembly).2. Set Temperature Set Point to 32°C (see Section 7 – Temperature Setting) and allow it tostabilize.3. Record set point temperature and sensor display temperature from the digital display onthe Control Panel. Record actual temperature from Calibrated Thermometer.4. Set Temperature Set Point to 37°C (see Section 7 – Temperature Setting) and allow it tostabilize.5. Record set point temperature and sensor display temperature from the digital display onthe Control Panel. Record actual temperature from Calibrated Thermometer.Adjustment of Sensor Display TemperatureCAUTIONThe sensor display temperature has been adjusted at the factory and should not require anyadditional adjustment. Adjustment may be made only when Calibration indicates more than0.2°C difference between Display Temperature and Actual Temperature (see Section 6 – Pre-Heat Temperature Calibration).1. Press both the Up (↑) and Down (↓) keys simultaneously until you see “LOC” equal to “5”(if “2”, change number using Up key to “5”).2. Press the (∞) key, then press the key repeatedly until you see “i.CA”.3. Add or subtract to the number in order to equal the standard temperature.4. After calibrating, press the (∞) key, then press both the Up (↑) and Down (↓) keyssimultaneously until you see “LOC”, which needs to be changed to “2”. Press the (∞) keyto finish.5. Recalibrate per Section 6 – Pre-Heat Temperature Calibration.Section 6 Validation and Calibration 16
