47. work Adaptor SNA10B optional for automatic calibration The calibration procedures described in the following section are a step by step manual procedures Since the controller needs 30 minutes to warm up an unit before calibration calibrating the unit one by one is quite inefficient An automatic calibration system for numerous quantities is available upon request Manual Calibration Procedures Perform step 1 to enter calibration mode Step 1 Set the Lock parameter to the unlocked condition LOCK NONE Press and hold the scroll key until 2 HL appears on the display then release the scroll key Press the scroll key for 2 seconds then release the display will and the unit enters calibration mode Perform step 2 to calibrate Zero of Ato D converter and step 3 to calibrate gain of A to D converter Step 2 Short the thermocouple inpt terminals then press scroll key for at least 3 seconds The display will blink a moment and a new value is obtained Otherwise if the display didn t blink or if the obtained value is equal to 199 9 or 199 9 then the calibration fails Step 3 Press scroll key until the display shows Send a 60mV signal to the thermocouple input terminals in correct polarity Press scroll key for at least 3 seconds The display will blink a moment and a new value is obtained Otherwise if the display didn t blink or if the obtained value is equal to 199 9 or 199 9 then the calibratio
