SPECIFICATIONS OF HI8615 & HI8615L TERMINAL BOARD CONNECTIONS Unscrew the 4 screws and remove the top cover. Range 4 to 20 mA / ±1000 mV Resolution 0.01 mA / 1 mV There are three cable glands on the transmitter Accuracy (@20°C/68°F) cover. -
Page 5: Ph Calibration With Automatic Temperature Compensation (Hi8614 & Hi8614L)
The wire between the transmitter and the pH CALIBRATION WITH AUTOMATIC recorder/indicator/controller should be a PVC TEMPERATURE COMPENSATION insulated two wire with a wire diameter of at (HI 8614 & HI 8614L) least 0.7 mm. This wire is fed through one of the smaller cable glands. - Page 6 Procedure For other buffer temperatures, refer to page 13 for the appropriate mA / pH reading. • Disconnect the +ve supply cable from "+VE LOOP" terminal and connect a 20mA • Rinse the electrode with tap f.s. ammeter between the +ve cable and water or distilled water and "+VE LOOP"...
