ALT (HI 93522 only) : enable the second function keys; the "ALT" tag turns on to indicate that the second functions are enabled. Note: The ALT key can be released before pressing the second function key for 1-hand operation. ALT/ CAL : press and hold for about 5 seconds to enter the Calibration mode (with reading within ±3°C range). (ALT +) BL : toggle the backlight ON and OFF. 7 OPERATIONAL GUIDE To switch the instrument ON, press the ON/OFF key. The thermometer will carry out a self diagnostic test routine, the LCD will show all segments for a few seconds (or as long as ON/OFF is held), followed by the percentage indication of the remaining battery life. The thermometer then enters normal measurement mode. If a temperature probe is plugged in, the meter displays the measured temperature. If no probe is plugged in, or if the reading is over-range, the display shows flashing dashes. If a measurement is slightly over the range of the meter specifications, the display will flash the closest full-scale value. To switch the meter OFF, press the ON/OFF key. °C/°F SELECTION Measurements can be displayed in either degrees Celsius or Fahrenheit. The meter is factory set to °C scale; to change the scale, press °C/°F key or (ALT+) °C/°F keys, HI 93510 / 510N HI 93522 or set the switch located in the battery compartment (HI 93512 only, see figure on page 10). HOLD and MR FUNCTIONS The HOLD function is activated by pressing the HOLD key. The measured temperature is held on the display until HOLD is pressed again. The "HOLD" tag blinks on the display while in HOLD mode. 8 Note: Although the display is frozen, internally the meter continues measuring and updating Hi/Lo and relative values. In HI 93522 only, the held value is also stored in non-volatile memory and can be recalled by pressing (ALT+) MR key. While the MR key is held, the "HOLD" tag lights up and the meter displays the stored value; when the MR key is released, after 1 second the meter returns to normal measurement mode. HIGH/LOW TEMPERATURES The maximum and minimum temperatures are continuously monitored and displayed on the lower portion of the LCD. Note: When the reading goes over-range or the probe is removed, the Hi and Lo values display dashes until cleared. CLEAR FUNCTION Upon pressing the CLR key, the High/Low values may be cleared at any time during measurement and the current reading is assigned to the highest and lowest temperature values for the displayed channel only. AUTO SHUT-OFF (HI 93510 and HI 93522) To save battery life, the HI 93510 and HI 93522 models are provided with an auto-off feature, which switches the instrument off after a certain period of nonuse. The auto-off delay time can be changed by the user (8 minutes, 60 minutes, or disabled). To access this feature, the HI 93510 is provided with an internal button located in the battery compartment (see figure on page 10). Unscrew the 4 screws on the back of the meter and select the desired auto-off time period by pressing the button and viewing the value on the LCD. Reattach the back making sure that the gasket is in place and tighten the 4 screws to ensure a watertight seal. 9 HI 93522 allows the user to select the auto-off time period through the keyboard; press (ALT+) AOFF to enter the mode, then set the desired auto shut-off interval (8 min, 60 min, or disabled) with the ALT key; release all buttons, wait a few seconds and the meter will return to normal measurement mode. BACKLIGHT FEATURE (HI 93510N and HI 93522) HI 93510N and HI 93522 models are provided with a Backlight feature, which can be easily activated through the keyboard by pressing the BL key or (ALT+)BL keys. HI 93510N HI 93522 Note: The backlight automatically shuts off after approximately 1 minute with no buttons pressed. BATTERY COMPARTMENT 10 2-CHANNEL MODELS (HI 93512 and HI 93522) HI 93512 and HI 93522 models can monitor two samples through two independent temperature channels (probes). The display will show the actual, Hi and Lo (or T1 and T2) values of the selected channel (T1, T2 or T1-T2). [. . . ] Operation of these instruments in residential area could cause unacceptable interferences to radio and TV equipments, requiring the operator to take all necessary steps to correct interferences. Any variation introduced by the user to the supplied equipment may degrade the instruments' EMC performance. To avoid electrical shock, do not use these instruments when voltages at the measurement surface exceed 24VAC or 60 VDC. To avoid damages or burns, do not perform any measurement in microwave ovens. Note: To clean the meters, do not use aggressive detergents. [. . . ]
