OPERATIONAL GUIDE POWER CONNECTION HI 982411-0 Connect a 2-wire power cable to the terminal strip while paying attention to the correct positive and negative contacts (12 VDC). HI 982411-1 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. DOSING CONTACT This contact (maximum 5A, 240VAC, 30VDC) is used for connection to an alarm or dosing system. The relay contact acts as a power switch for the controlling device. OPERATING THE METER All operations are controlled via the front panel keys and trimmers. [. . . ] Using a small screwdriver adjust the "SET" trimmer until the required value is displayed.
