Monarch 1071-8041-210, Monarch 314 Datalogging Humidity Temperature Meter Operating Instructions

MODEL 314 DATALOGGING HUMIDITY TEMPERATURE METER

4.0Operating Instructions:

4.1Preparation for Measurement

Measurement of ambient humidity and temperature (T1) may be made with the probe clipped to the instrument or hand held remotely.

For measurement of a second temperature, plug a Type K thermocouple into the socket marked T2, taking care to observe the polarity of the thermocouple pins.

4.2Power

Press the button to turn the thermometer ON or OFF.

When first powered on, the display will show how much memory

space is available for use.

Example: Display at right indicates 16,000 records of available memory.

4.3Humidity and Temperature (T1) Measurement

Place the humidity temperature probe in the environment to be measured. Be sure to allow sufficient time for the sensors to respond to ambient conditions. This time will be dependent on the amount of air circulation through the probe mask. (See Section 2.0: Response Time.)

4.4Selecting the Temperature Scale

When first turned on, the instrument defaults to reading in Celsius (°C). To display readings in Fahrenheit (°F), press the °C / °F button. To return to readings in Celsius (°C), again press the °C / °F button. The instrument remembers the scale setting when last turned off and powers on in that setting the next time.

4.5Data-Hold Function

The present reading is held on the display by pressing the HOLD button. Pressing the HOLD button again releases the hold function and returns the instrument to continuous reading.

In the HOLD mode, the MAX MIN, °C / °F and UREL buttons are disabled, as indicated by two consecutive beeps when pressed.

4.6Clock Setup

To set the real time clock:

1. Press and hold the MAX MIN button and then power on the meter.

2.Press TIME (clock).

3.Press REC (ν) or °C/°F (π) to increase or decrease the number.

4. Press TIME to move to the next item. The adjusting order is: year; month; day; hour; minute.

5. Press TIME again after the last setting to complete the process. To abort during a setup process, press the button.

4.7Time Function

Once setup, pressing the TIME button displays time as follows: top of the LCD – year; bottom left of the LCD - month and day; bottom right of the LCD - hour and minute. Press the TIME button or any other button to exit this mode. This operation will not interrupt the recording and MAX/MIN operation.
