If any damage has occurred during shipment, immediately notify your Dealer or the nearest Hanna Customer Service Center. [. . . ] In addition, the Battery Error Prevention System (BEPS) automatically turns the meter off for avoiding erroneous readings caused by low voltage level. The built-in temperature and conductivity sensors are protected inside the cell cup. Reproduction in whole or in part is prohibited without the written consent of the copyright owner. Hanna Instruments reserves the right to modify the design, construction and appearance of its products without advance notice. OPERATIONAL GUIDE To turn the meter on and check the battery status Press and hold the MODE button for 2-3 seconds. All the used segments of the LCD will be visible for a few seconds, followed by a percent indication of the remaining battery life (eg. Taking measurements Rinse and fill the cell cup with the solution to be tested. The measurements should be taken when the stability indicator on the top left of the LCD disappears. The EC (or TDS) value automatically compensated for temperature variations, is shown on the LCD together with the temperature of the sample. To change the temperature unit To change the temperature unit (from °C to °F), from measurement mode press and hold the MODE button until TEMP and the current temperature unit are displayed on the lower LCD (eg. Use the SET/HOLD button to change the temperature unit, and then press the MODE button twice to return to normal measurement mode. To freeze the display Press and hold the SET/HOLD button until "HOLD" appears on the secondary display. To turn the meter off Press the MODE button while in normal measurement mode. Notes · Before taking any measurement make sure the meter has been calibrated. · If measurements are taken in different samples successively, rinse the cell cup thoroughly with water, and then with some of the sample to be measured. CALIBRATION For better accuracy, frequent calibration of the instrument is recommended. In addition, the instrument must be recalibrated whenever: a) After testing aggressive chemicals. To change the TDS factor (CONV) and the temperature compensation coefficient (BETA) · From measurement mode, press & hold the MODE button until TEMP and the current temperature unit are displayed on the lower LCD (eg. · Press the MODE button again to show the current conversion factor (eg. · Press the MODE button to show the current temperature compensation coefficient (eg. Calibration procedure · From measurement mode, press & hold the MODE button until CAL is displayed on the lower LCD. [. . . ] Remove the screw and the washer in the battery compartment and carefully replace the 4 batteries located in the compartment, while paying attention to their polarity. CE DECLARATION OF CONFORMITY Replace the washer and tighten the screw in the compartment; replace the bottom, ensuring that the gasket is in place before tightening the screws.
