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.
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.
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 TEMP TIME LOG ==01== 0010 10-01-96 0002M *00.18 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.
Press the UP key to view the time. TIME UP Press the UP key again to view the temperature. °C CH UP 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.
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). The memory can be downloaded to your PC through the HI 9200's RS 232 port. During the data transfer the instrument displays the message "r 232".
Data transmission from the instrument to the PC is now much easier with new HI 92000 Windows® compatible application software offered by Hanna Instruments. HI 92000 allows you to use the powerful means of the most spread sheet programs (e.g.Excel©, Lotus 1-2-3©). Simply run your favorite spread sheet and open the file downloaded by HI 92000. It is then possible to make any elaboration available with your software (e.g. graphics, statistical analysis).
MEMORY ORGANIZATION (HI 92810 & HI 92840 ONLY) Capacity: 16,000 data samples, divided into 16 pages. Data capacity per page: 1000 data samples with 1 channel monitored; 500 data samples with 2 channels monitored (four channels versions only); 250 data samples with 3 or 4 channels monitored (four channels versions only). Each time a new logging period starts, it automatically starts from a new page.
PRINTER MAINTENANCE TO CHANGE THE INK CARTRIDGE When printouts become faint, it might be necessary to change the ink cartridge. Contact your Hanna authorized center. TO INSERT THE PAPER ROLL The HI 92710, HI 92740, HI 92810 and HI 92840 use plain paper rolls 38 mm width (HI710034). To insert a new roll is very easy. Open the paper cover pulling it gently.
