5 / 12 page 5 421502 Ver. 1.9 12/05 Elapsed Timer The Timer (third display on bottom right of LCD) displays Clock or Elapsed Time and is a convenient way to see when Min and Max temperatures occurred. Each time new Min or Max temperature values are stored, the timer/clock value for the Max or Min temperature is also stored for later recall. Real time can be entered by setting the meter's clock to the current time (set Hours:Mins display using the MIN/SEC key). To use the clock as an elapsed timer, first reset the clock to zero in Set Mode (see next section). The timer will begin counting as soon as it is set in SET mode. SET Mode (for Relative Mode, HI/LO Alarm setpoints, and Clock/Timer settings) Manually setting the Relative Values in SET Mode Press the "SET" key once and the display will go to all dashes "======". Enter the relative value using the meter's keys which double as numeric keys. USE LEADING ZEROS SINCE DISPLAY IS 5-DIGITS. Once the Relative value is entered, press the ENTER key FOUR times to return to normal operation. Meter will now display Actual Temperature minus Relative Temperature Setting the Timer/Clock in SET Mode Press the "SET" key and then the "ENTER" key. Next key in the Hours, Minutes, and Seconds (HH:MM:SS) via the overlay numeric keys. When editing is complete, the clock will begin counting. Press the "ENTER" key three times to return to normal meter operation. Now use the SEC/MIN key to toggle between Hours/Minutes and Minutes/Seconds display. Alarm HI/LO Limit Programming in SET Mode Press the "SET" key once and then the "ENTER" key twice. Key in the desired HI Alarm value (high temperature at which the meter will audibly alert the user) via the overlay numeric keys. Now press the "ENTER" key once. Next, key in the LO Alarm Limit value (low temperature at which the meter audibly alerts the user). Press the ENTER key once to return to normal operation. After exiting the SET mode, press the "HI/LO Limits" key to activate the Alarm, the audio icon on the LCD tells you that the Alarm is now armed and will alert you if HI/LO limits are encountered. Second Display Input Selection "T1, T2 or T1-T2" Pressing the "T1 T2 / T1 - T2" key (the key with the minus sign printed over it) permits the user to select the thermocouple input configuration which will be reflected on the meter's Second Display (lower left LCD). Choose "T1 or T2" to show either thermocouple input 1 or 2 respectively. Select "T1 - T2" to display the difference between the two thermocouple input temperatures. In T1 - T2 mode, a reading of zero indicates that both thermocouples are reading the same temperature. "K/J" Key (Selecting theThermocouple Type for the T2 Main Display) For the type of thermocouple that is plugged into the T2 terminal on the meter, select K or J (to match input) by toggling the "K/J" key. The meter remembers this selection upon power OFF. HI/LO Alarm Limits Mode Press the "HI/LO Limits" key to arm the HI/LO Alarms (the audio speaker icon will appear on the right side of the LCD). When the actual temperature meets or exceeds the user programmed temperature limits a continuous alert tone will be heard. To disarm or silence a tripped Alarm press the HI/LO Limit key again (the audio display icon will disappear). |
