If any damage has occurred during shipment, immediately notify your Dealer or the nearest Hanna Customer Service Center. [. . . ] HI 98332700 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 if alarm is active. Positive 230 VAC Negative 115 VAC ----Neutral ----Protection Earth the power input is internally protected by a 400 mA fuse 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.

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. ALARM CONTACT Use this contact (maximum 5A, 240VAC, 30VDC) for connection to an alarm or dosing system. 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. [. . . ] 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. [. . . ]
