User manual HANNA INSTRUMENTS HI 93530N

[. . . ] Damages 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 failure. First obtain a Returned Goods Authorization number from the Customer Service department, then return the instrument with the Authorization number included along with shipment costs prepaid. [. . . ] 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. Note: When the reading goes over-range or the probe is removed, the Hi and Lo values display dashes until cleared. CLEAR FUNCTION (not for HI 93530 and HI 93530N) 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. 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 reading is over-range, the display shows flashing dashes. If a measurement is slightly over the range of the meter specifications, the display flashes the closest full-scale value. To switch the meter OFF, press the ON/OFF key. Note: The meters are provided with an acoustic signal feature activated when buttons are pressed, which can be disabled using a switch located in the battery compartment (see figure on page 12). °C/°F SELECTION Measurements can be displayed in either degrees Celsius or Fahrenheit. Pressing CLR will also set the reference to the current temperature. In relative mode, the main body of the LCD shows the difference from the reference temperature. The lower portion displays the current temperature for the selected channel. When average mode is entered, the "AVG" tag lights up and the current value is set as the new beginning value. The average can be reset by pressing CLR while in the average mode. In average mode, the main body of the LCD shows the average temperature, while the lower portion displays the current temperature for the selected channel. BATTERY COMPARTMENT See "Battery replacement" section for back cover removal/installation. 2-CHANNEL MODELS (HI 93532, HI 93532N & HI 93532R) HI 93532, HI 93532N and HI 93532R models can monitor two samples through two independent temperature channels (probes). The display will show the actual, Hi and Lo values of the selected channel (T1, T2 or T1-T2). The corresponding tags will light up to inform the user. 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. 15 To select the desired channel, use the T1/T2 key. 14 The average value is lost and will not restore even if the condition restores. To start the average cycle again, either press CLR or reenter the average mode. · While in T1-T2 (HI 93532R only), pressing DISP will switch between 4 displays: SERIAL PORT COMMUNICATION (HI 93531R & HI 93532R only) HI 93531R and HI 93532R feature an RS232 output for transferring measurement data (once every second for HI 93531R and once every 2 seconds for HI 93532R) to devices provided with RS232 input (PC or printer). The communication protocol has been designed to transmit to the receiving unit all the displayed information. The communication is unidirectional (meter to receiving unit only) and the transmissions consist in a 32-character ASCII string, compatible with our optional HI 92000 software.
