The temperature probe can be used independently totake temperature measurements, or it can be used in conjunction withthe pH electrode to utilize the meter's ATC capability. If the probe isdisconnected, temperature can also be setmanually with the UP and DOWN keys. Toswitch the instrument on, press and hold theON/OFF key for a fraction of a second. Themeter has a built-in protection against electro-magnetic interference and the delayed responseof the keys assures that the commands are notmistaken for stray signals.HI 9110 and HI 9210:Connect the pH electrode to the BNC connector on the top of theinstrument and press the ON/OFF key.HI 9210N and HI 9023CN:Connect the pH/ C electrode to the DIN connector on the top ofthe instrument and press the ON/OFF key.OPERATIONAL GUIDEOPERATIONAL GUIDEOPERATIONAL GUIDEOPERATIONAL GUIDEOPERATIONAL GUIDEON/OFF
