[. . . ] This warranty is limited to repair or replacement free of charge. Damage due to accidents, misuse, tampering or lack of prescribed maintenance are not covered. If service is required, contact the dealer from whom you purchased the instrument. If under warranty, report the model number, date of purchase, serial number and the nature of the problem. [. . . ] °C/°F unit for temperature and dewpoint (HI 9565 only) readings; 2. disable/enable (20 minutes) auto-off feature; 3. To access these features, remove the battery cover on the back of the meter and extract the battery. Select the desired settings, insert the battery and close the cover. ERROR MESSAGES All modes of operation · Blinking values denote indicative readings. This will occur for the RH display and dewpoint display if the measured temperature is less than 0°C or greater than 60°C. · A blinking full scale value means that the reading is out of range. No data currently available to be displayed. If dashes are shown in MIN/MAX mode, press CLEAR to reset the values. No probe connected or invalid calibration data retrieved from the probe. The meter continues checking probe until error condition is corrected. Error in temperature measurement: the reading is extremely over range or the probe is damaged. Error in RH measurement: the sensor is wet or the probe is damaged. Calibration mode, upon pressing CAL to accept value The measured RH is greater than the set value by more than 9% RH. The measured RH is lower than the set value by more than 9% RH. The calibration temperature is too high. RH CALIBRATION The RH calibration is a single point procedure (offset). · To enter calibration: from normal mode press and hold the CAL button for approx. 5 seconds, until the display shows the "CAL" message. The meter will display "OFS" and then flash the default value (60% RH) for calibration. · To switch the display to show temperature, dewpoint (HI 9565 only) or return to RH reading, press RANGE. Note: A blinking full scale value means that the reading is out of range. · To freeze the current measurement on the LCD, press HOLD. The "H" tag will blink and the meter continues measuring and updating the min/max values internally. Note: Even in Hold mode, the user can still scrow through the channels with RANGE, to show the status of the meter when HOLD was pressed. Note: The CLEAR and CAL keys are disabled when the meter is in Hold mode. [. . . ] Press ON/OFF to power the meter on and return to normal mode with the previous calibration data. · To clear any previous offset calibration value, while in calibration mode, press and hold the ON/OFF key and then CAL. The meter will display the "CLr" message and then "Str", before returning to the normal mode. Note: If a weak battery is detected or the probe is removed during calibration, the meter will abort the calibration procedure and shut off. The calibration temperature is too low. BATTERY REPLACEMENT The BEPS (Battery Error Prevention System) recognizes two different low battery levels. [. . . ]
