If any damage has occurred during shipment, immediately notify your Dealer or the nearest Hanna Customer Service Center. [. . . ] 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. Recommendations for Users Before using these products, make sure that they are entirely suitable for the environment in which they are used. 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. To avoid electrical shock, do not use these instruments when voltage at the measurement surface exceeds 24 VAC or 60 VDC. To avoid damage or burns, do not perform any measurement in microwave ovens.

OPERATIONAL GUIDE POWER CONNECTION HI 983320-0 Connect a 2-wire power cable to the terminal strip while paying attention to the correct positive and negative polarities (12 VDC). HI 983320-1 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. Press the "MEAS" key. [. . . ] · If a more thorough cleaning is required, brush the metal pins with very fine sandpaper. · After cleaning, rinse the probe with tap water and recalibrate the meter. · When not in use, clean the probe before storing it.
