Please read this instruction manual carefully before using the instrument. This manual will provide you with the necessary information for the correct use of the instrument, as well as a precise idea of its versatility. [. . . ] This can be avoided by applying an external voltage to the unit before replacing the batteries. + TIME INTV RANGE SETTING DATE, TIME & PRINTING/LOGGING INTERVAL WITH HI 91610 Press the ALT and TIME keys simultaneously. The display will show the previously memorized date with the year blinking on the secondary display (as the last two digits of the year, e. g. 95 = 1995). Any interval can be selected from among 1, 2, 5, 10, 15, 30, 60, 120 and 180 minutes by using the UP and DOWN keys. UP DOWN Once the desired interval is selected, press RANGE once to memorize it. The hour will start blinking. ALT UP DATE RANGE TIME Use the UP or DOWN keys to select the correct year. RANGE UP DOWN To select the hour, press the UP or the DOWN keys (24 hour clock). When the year is selected, press the TIME key once to memorize it. The month will start blinking. UP DOWN To memorize the hour press RANGE once again. This also displays the printing/ logging interval. PRINTING/RECORDING WITH HI 9161 To print the measured values press PRINT. Each printout provides the following information: a ­ Current sample number b ­ Date (DD-MM-YY) 0001 c ­ Time (HH. MM) d ­ RH% value e ­ Temperature value <> PRINT TIME a 10-01-96 *10. 59 65. 6 RH% 25. 0 °C TIME INTV b c d e To view the date, press the UP key when the LCD is displaying time. DATE UP RECORDING AT AN INTERVAL Set the appropriate logging interval, the press LOG to enter the recording mode. The log number and the recording interval will appear for a few seconds on the secondary display to indicate the operational mode. LOG To view RH% on the primary display press RANGE. LOG INTV RANGE To view temperature on the primary display when in RH% mode, press RANGE again. °C The meter will print the current measurements and with the indicated printing interval thereafter until the ON/OFF key is pressed. The printout provides the following information: c a b 10-01-96 --01-<> 0001 0005M *11. 05 65. 6 RH% 25. 0 °C d e f g RANGE If "----" is displayed, no probe is connected or the probe cable is broken. Note: The RH% value is displayed without any symbol on the primary display. The temperature value is always displayed together with the "°C" or "°F" symbol. a ­ Curernt log number b ­ Current sample number in that particular log c ­ Date (DD-MM-YY) d ­ Printing interval in minutes e ­ Time (HH.

LOG 16 17 Press the RANGE key to read the temperature on the primary display. PRINTING/LOGGING WITH HI 91610 RANGE If no key is pressed, after approximately 5 minutes, the meter goes in standby mode to save the battery life. Note: If PRINT is pressed while still in recording mode, a printout is produced without affecting the running number. 10-01-96 0005M -- 05 -*11. 51 65. 2 RH% 25. 0 °C To print the values shown on the display, press PRINT. PRINT PRINT Printing during recording This function can be activated in normal operation mode as well as during logging (and scanning) modes. When in the measurement mode, each printout provides the following information: a ­ Running sample number b ­ Date (DD-MM-YY) 15-01-96 0001 *11. 20 c ­ Time (HH. MM) 65. 6 RH% d ­ RH% value 25. 0 °C e ­ Temperature value <> a b c d e TO STOP RECORDING To exit the recording mode, press ON/OFF. The instrument will make one final exit printout. 10-01-96 --01 -<> 0006 0005M *12. 01 65. 1 RH% 25. 0 °C LOGGING MODE WITHOUT PRINTING This function is particularly useful when measurements have to be taken continuously even in the absence of an operator over a long period of time. The current log number and remaining page numbers will appear for a few seconds on the display to indicate the correct operational mode. The printer will print a complete set of data and the "LOG" symbol will appear on the secondary LCD. ON/OFF The running log number can be reset by simply removing the batteries. ALT UP DOWN RANGE TIME LOG Press the ALT and PAPER keys at the same time and the "LOG" symbol on display will start to blink. PRINT PAPER ALT UP If no key is pressed, after approximately 5 minutes the display will switch itself off but the logging function remains active. 18 19 Each printout provides the following information: To reactivate the display press the TIME key. Notes: · Once in the logging mode, the interval cannot be changed. Exit the logging mode (press ALT and LOG together) and then set the new interval. · If the PRINT key is pressed while in logging mode, a printout is produced without affecting the running sample number. PRINT TIME a b 14-01-96 --01-<> 0015 0001M *15. 01 65. 9 RH% 25. 4 °C c d e f SAMPLE NUMBER During logging it is possible to know the running sample number. Press the LOG key twice and the display will show the running number in the current log together with sample number symbol "Sn". g a ­ Current log number b ­ Current sample number (in that particular log) c ­ Date (DD-MM-YY) d ­ Printing interval in minutes e ­ Time (HH. MM) f ­ RH% value g ­ Temperature value 2x LOG LOG It is always possible to switch from the logging with printing function to logging without printouts. Press ALT and PAPER at the same time and the "LOG" symbol will start blinking to indicate that the data is now stored into memory but no longer printed. PRINT PAPER LOGGING MODE WITH PRINTING This function is useful in a variety of applications from unsupervised monitoring to satisfying regulatory requirements. In addition to the printouts, the measurements are also stored into the memory. [. . . ] During logging, the meter automatically returns to the oldest page in the memory and if it contains data, it will overwrite it. In this case the first log will not correspond to the oldest set of data. Save data into a PC if you need to keep a record and then remove the batteries for about 1 minute. Remember to reset time and date, once the batteries have been reinserted. A 12 Vdc power source can also be used to power the unit. [. . . ]
