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.
The HI 93551R, HI 93552 and HI 93552R allow the user to select the auto-off time period through the front 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.
The average mode will calculate the average for a period of up to 24 hours. If a different mode is selected for that channel, the average will no longer calculate and the value will be lost. At the end of the 24 hour period, the "AVG" tag will blink to indicate that sampling has stopped, and the displayed value is the last average calculated. If a probe is removed or over-range is reached while in average mode, the display shows flashing dashes and blinking "AVG" tag.
USER CALIBRATION BATTERY REPLACEMENT The HI 93551N, HI 93551R, HI 93552 and HI 93552R models can be calibrated at 0°C by using an ice bath. • Prepare an ice bath with approximately equal volumes of distilled water and chopped ice made from distilled water. • Immerse the temperature probe in the center of the ice bath, taking care not to touch the ice with the probe tip. • Ensure that the meter is measuring a temperature within ±3°C.
