Operating Instructions

Power-Up: Press the power button to turn the Humidity Temperature Meter ON or When powered on, the LCD will show how much memory space is available to use. For example, it indicates that there are 16,000 records memory space available.

Humidity and Temperature Measurement: For measurement, place the sensor probe in the test environment.
Connecting the Thermocouples (T2 channel): For measurement, plug the thermocouple probe into the input connector.
Selecting the Temperature Scale: When the meter is first powered on, the default scale setting is set at Celsius (°C) scale. The user may change it to Fahrenheit (°F) by pressing “°C/°F” button and vice versa to Celsius. Next time you power on, the scale setting will be the same as which when you powered off last
Data-Hold Operation: The user may hold the present reading and keep it on the display by pressing the “HOLD” button. When the held data is no longer needed, one may release the data-hold operation by pressing “HOLD” button again. When the meter is under Data Hold operation, the “MAX MIN” and “°C/°F” button are disabled (when you press “°C/°F” and “MAX MIN” button in HOLD mode, there will be two continuous beeps). To exit the MAX/MIN mode, one may press and hold “MAX MIN” button for two seconds.
Data Logger: When pressing the “REC” button, the meter will start recording, pressing the “REC” button again will stop recording, If you want to clear the memory, power off the meter, then press and hold “REC” button and then press power button, then release all buttons, then LCD will show “CLR” to clear the memory.

Clock Setup

  • Press and hold “MAX MIN” button and then power on the meter.
  • Press “TIME” (clock).
  • Press “REC” ▲ or “°C/°F” ▼ to increase or decrease the number, press “TIME”(clock) to adjust next item. The adjusting order is year-month-day-hour-minute, then press “TIME” (clock) to finish adjusting. If you want abort during a setup process, press power button to cancel.

Recording Interval Setup:

  • Press and hold “MAX MIN” button and then power on the meter.
  • Press “HOLD”(INTV).
  • Press “REC” ▲ or “°C/°F” ▼ to increase or decrease the number, press “HOLD” (INTV) to adjust next item, then press “HOLD” (INTV) to finish. If you want abort during a setup process, press power button to cancel.

Time Operation: When pressing the “TIME” button, the LCD will display time, it will show year on top of the LCD, show month and day on the left bottom of the LCD, show hour and minute on the right bottom of the LCD. Press “TIME” button or any other button to exit this mode. This operation will not interrupt the recording and “MAX MIN” operation.
MAX/MIN Operation: When pressing the “MAX MIN” button the meter will enter the MAX/MIN mode. Under this mode, the maximum value/minimum value is kept in the memory simultaneously and updated with every new data point. When the MAX symbol is displayed, the Maximum is shown on the display. Press “MAX MIN” again, then the MIN symbol is on the display and the minimum reading is displayed. Press “MAX MIN” again, MAX, and MIN will blink together. This means that all data is updated in the memory and the reading is the present temperature. One may press “MAX MIN” to circulate the display mode among these options. When the meter is under “MAX MIN” operation, “ °C/°F ” button is disabled (when you press “ °C/°F ” button in “MAX MIN” mode, there will be two continuous beeps). To exit the MAX/MIN mode, one may press and hold “MAX MIN” for two seconds.
Auto Power Off: By default, when the meter is powered on, it is under auto power off mode. The meter will power itself off after 30 minutes if no key operation and no RS232 communication and no recording. The combination of power on can disable auto power off. One may press and hold “HOLD” button and then power on the meter and there will be two successive beeps to indicate that auto power off is disabled and the will not show up.

Low Battery Condition: When the battery voltage is under proper operation requirement, the battery symbol will show on the LCD and the battery needs to be replaced with new one.
Digital Output:

The Digital Output is a 9600 bps N 81 serial interface.
