OPERATIONAL GUIDE POWER CONNECTION HI 983327-0 and HI 98332700 Connect a 2-wire power cable to the terminal strip while paying attention to the correct positive and negative contacts (12 VDC). HI 983327-1 Connect a 3-wire power cable to the terminal strip while paying attention to the correct earth, neutral and line contacts (115/230 VAC). Notes: · All external cables connected to the rear panel should end with wire lugs. · It is recommended to cover the unused terminals with insulating tape. · At start up the meter needs a few seconds to stabilize. Wait until a stable reading is displayed. ALARM CONTACT Use this contact (maximum 5A, 240VAC, 30VDC) for connection to an alarm or dosing system. The unit acts as a switch to control an external device. OPERATING THE METER All operations can be controlled via front panel keys and trimmers. "SET" and "MEAS" LEDs light up to indicate which is the operating function. Make sure that the meter is calibrated and the Setpoint is properly selected before performing any measurement. Install the probe in the fittings or immerse it in the solution to be monitored, while making sure that metal pins are completely submerged. The LCD will show the conductivity value of the solution in mS/cm unit. Any initial variation on readings may be due to temperature compensation. The "ALARM" LED will light up when the alarm contact is losed, to indicate an EC value higher than selected setpoint.
