OPERATIONAL GUIDE POWER CONNECTION HI 983317-0 and HI 98331700 Connect a 2-wire power cable to the terminal strip while paying attention to the correct positive and negative polarities (12 VDC). HI 983317-1 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. Any initial variation on readings may be due to temperature compensation. The "ALARM" LED will light up when the alarm contact is closed, to indicate an EC value lower than selected setpoint. CALIBRATION Make sure the meter is in the measurement mode (the "MEAS" LED lights on). Immerse the probe in HI 7039 (5. 00 mS/cm) calibration solution.
