If any damage has occurred during shipment, immediately notify your Dealer or the nearest Hanna Customer Service Center. [. . . ] HI 98331700 is provided with a DC/DC converter which isolates the measure system from the external power supply. The models are panel mounted with membrane keypads on the front panel and an easy-to-read LCD display. All the meters automatically compensate for the temperature variation. Measurements are highly accurate and the meters can be calibrated at one point. Power supply, wiring and selection are made via the plugin terminal blocks on the rear panel. LED indicators on the front panel identify whether the controller is in set or measurement mode, and dosing mode. Side view of the panel-mounted unit Supplied adjustable location brackets allow the controller to slide into the cutout and will hold the unit securely in place. 95 mm (3. 74") is the minimum amount of space required to install the controller. 0. 25/4mm 0. 01/0. 160" ADJUSTABLE LOCATION BRACKET 79mm 3. 11" 76mm 3" 95mm MIN 3. 74" L1: Positive 230 VAC L2: Negative 115 VAC L3: -------Neutral L4: --------Protection Earth Note: the power input is internally protected by a 400 mA fuse 2.

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. 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. ACCESSORIES HI 7632-00 EC probe HI 70039P 5. 00 mS/cm (5000 µS/cm) calibration solution, 20mL sachet (25 pcs) HI 7039M 5. 00 mS/cm (5000 µS/cm) calibration solution, 230mL bottle HI 7061M Electrode cleaning solution, 230 mL bottle HI 710005 12 VDC power adapter, US plug HI 710006 12 VDC power adapter, European plug HI 710012 12 VDC power adapter, Australian plug HI 710013 12 VDC power adapter, Southern Africa plug HI 710014 12 VDC power adapter, UK plug HI 731326 Calibration Screwdriver (20 pcs) HI 740146 Mounting brackets CE DECLARATION OF CONFORMITY Shake briefly and wait for reading to stabilize. Using a small screwdriver adjust the calibration trimmer until the meter displays "5. 00" on the LCD. The display will show the default or previously adjusted value for the setpoint. Using a small screwdriver, adjust the "SET" trimmer until the required limit value is displayed. PROBE MAINTENANCE SPECIFICATIONS HI 983317 Range 0. 00 to 10. 00 mS/cm Resolution 0. 01 mS/cm Accuracy (@ 20°C) ±2% f. s. Setpoint Adjustable through multiturn trimmer Alarm Condition LED ON and alarm contact closed when measured EC value is lower than setpoint Alarm Output 2-contact relay, no fuse protected. [. . . ] Operation of these instruments in residential areas could cause unacceptable interferences to radio and TV equipment. The metal band at the end of the probe is sensitive to electrostatic discharges. During operation, ESD wrist straps should be worn to avoid possible damage to the probe by electrostatic discharges. Any variation introduced by the user to the supplied equipment may degrade the instrument's EMC performance. [. . . ]
