OPERATIONAL GUIDE INITIAL PREPARATION Each meter is supplied complete with batteries. Remove the back cover, unwrap the batteries and install them while paying attention to their polarity. To switch on, press the ON/OFF key on the front of the unit. HI / LO MEMORIES (for HI 9060 only) The maximum and minimum temperatures are monitored throughout a continuous measuring process. The values may be recalled or cleared at any time during the measurement.
HOLD MODE (for HI 9060 only) The reading hold function is activated by the HOLD key. The measured temperature is frozen on the display when this function key is pressed. A blinking "M" on the display indicates the operating mode. HI 9060 and HI 9061 stop to operate when the low battery signal is detected. The user is warned by the code "Eb". HI 91541 displays "BAT" when the batteries are run down. °C M See also the Battery Replacement section on page 14.
DISPLAY CODES GUIDE Your thermometer is factory programmed to diagnose a fault or warn of low battery levels. This is indicated by the error codes on the LCD. Moreover, self-explanatory symbols are used to remind the user of the operating mode or conditions. DISPLAY Er (for HI9060 and HI 9061) ----(for HI 91541) Eb DESCRIPTION The probe is not connected to the instrument or the reading is out of range. Battery weak, need to be replaced.
