TABLE OF CONTENTS Preliminary Examination . . . . . . . . . . . . . . . . . . . . . . . . . . . . . [. . . ] This now shows the date in which the log has started. ALT DATE TEMP Press the UP key and the time of the most recent sample will be displayed. TIME UP 20 Press the UP key and the temperature will be displayed. °C CH Continue pressing the UP key to display one by one all the memorized data of the same log in the above sequence i. e. Press the DOWN key to revert back to sampling time and move back through samples. To exit from the recall mode press the LOG key. LOG Note: this mode will not alter data into memory 21 TO PRINT STORED DATA Once a log number is selected by using ALT and DOWN keys, as detailed in the chapter "TO SCAN STORED DATA ON DISPLAY" you can print all or part of that log section by using the ALT and the PRINT keys. The printer will start to print the logged section beginning with the selected sample number without altering the content of the memory. Note: It is always possible to print only the sample shown on the display by pressing the PRINT key. ALT DOWN PRINT ALT PRINT Note: Before proceeding with printing, make sure there is enough paper for the data to be printed. When the paper is finished the meter will not advise the operator and the printouts could be lost. If this happens, stop the printer by PAPER pressing the ALT and PRINT the PAPER keys simultaneously. Insert a new paper roll and repeat the instruction above starting from the last printed sample number (see chapter "PRINTER MAINTENANCE" on page 30 for changing paper roll). 22 WORKING SAMPLE (HI 92810 and HI 92840 only) The following is a step by step procedure of a typical monitoring situation where we have assumed that you have already inserted the batteries and set the date and time correctly. It is an example of a meter used to monitor and store every 2 minutes. The meter will log 10 samples but print only 3, display the data contained in sample number 1 and print samples 5 through 10. Example: Step One - Setting the printing/logging interval at 2 minutes: Press ALT and TIME keys twice. The time will appear on the primary display with a number representing the printing/logging interval blinking. ALT UP INTV TIME TEMP TIME Press either the UP or DOWN keys until a blinking "2" appears. TIME INTV UP DOWN Press ALT and TIME keys to exit. The display will now show the current time together with the selected interval of 2 minutes. ALT UP INTV TIME TEMP TIME Step Two - Entering the log mode: Press ALT and LOG keys. Initially, "L 01" will appear on the primary display. ALT UP DOWN LOG TEMP TIME LOG 23 The meter is now in the printing/logging mode utilizing log number 1, page 16. "LOG" and P 15 shown in the secondary display indicate that the meter has entered the log mode, and has 15 available pages of memory remaining. After the initial printout, the time and printing/ logging interval will reappear. TIME INTV Press the LOG key to view the running log and page numbers. LOG LOG Press the LOG key again to view the running sample number LOG LOG Step Three - Stopping the printer during the log mode: After the third printout is completed, press the ALT and PAPER keys. At this point the meter will continue to log data every 2 minutes but will no longer print any information. "LOG" will keep blinking on the secondary display for the remainder of "L 01" (log number 1). PRINT PAPER LOG ALT UP Note: If the display has shut off press the TEMP key to reactivate it, then press the LOG key twice to view the running sample number. 24 Step Four - Leaving the log mode: Once the number of samples stored in memory has reached 10, press the ALT and LOG keys. The meter will exit the log mode after generating a log exit status printout. ALT UP DOWN ==01== 0010 10-01-96 0002M *00. 18 TEMP TIME LOG Step Five - Reviewing the stored data in sample number 1: Press LOG key to enter the memory recall mode. The next available log and page number will be shown on the display. LOG Press the ALT and DOWN keys until the number 10 and "L1" appear, indicating that a total of 10 samples were recorded in log number 1. ALT DOWN To view the data stored in sample number 1 first use the UP and DOWN keys to scroll through the sample numbers. UP DOWN Once the number is displayed, press the ALT and TEMP keys. The date during which that sample was taken will appear first. DATE ALT TEMP 25 Press the UP key to view the time. TIME UP Press the UP key again to view the temperature. °C UP CH With HI 92840 when more than one probe have been connected, press the UP key to view the other channels values. Step Six - Printing the stored data (samples 5 through 10): Press and hold the ALT key and press the DOWN key until the total number of samples recorded in log number 1 is displayed. ALT DOWN Scroll through the sample numbers by using either the UP or DOWN keys until number "5" appears. UP DOWN Press the ALT and PRINT keys. The meter will print out samples number 5, 6, 7, 8, 9 and 10 consecutively. PRINT ALT 26 DATA TRANSFER TO PC HI 92810 and HI 92840 provide infrared emitting circuitry. Set the meter to the TIME mode and place your datalogger on a HI 9200 Infrared Transmitter (ensuring that the TIME two infrared LEDs are placed on top of each other).

For this reason, Hanna offers a wide line of NTC Thermistor sensors that can be custom mounted in almost any situation. Select the sensor that matches your application, attach it to the RCA adaptor and plug it into the meter. You now have a temperature sensor that is custom fit to your requirements. [. . . ]
