Mon-T Temperature Logging Range Parameters

Program Menu > Mon-T Temperature Logging Range Parameters

The parameters discussed here are only present in the Temprecord Mon-T logger. When the parameters for Temprecord Mk1 through Mk3a loggers are edited, these parameters do not apply and will not show in the parameters dialog.

The Mon-T logger allows the user to trade off temperature resolution against temperature range. This is achieved by allowing the user to specify the minimum temperature logged and the resolution. If a small value of resolution is specified, e.g. 0.05C, the logger will only record over a smaller range. The table below shows the temperature logging range that results from various settings of these controls

Minimum Temperature	Resolution	Range

-40	0.50	-40.00 to +86.50
-20	0.20	-20.00 to +30.60
-15	0.10	-15.00 to +10.30
- 5	0.05	- 5.00 to +7.65

Minimum Temperature

This is the lowest temperature the Mon-T logger can record. It can be set to any value within the specified temperature range of the logger. It serves as the starting point for the logging temperature range.

Resolution

The size of the steps between one temperature and the next. The higher the resolution, the smaller the logged temperature range. The resolutions available depend on the logger temperature units:

Resolution	Range (Celsius)	Range (Fahrenheit)

1.00	not available	253.00 F
0.50	126.50 C	126.50 F
0.20	50.60 C	50.60 F
0.10	25.30 C	12.30 F
0.05	12.65 C	not available

Maximum Temperature

This is the highest temperature the Mon-T logger can record. It is calculated from the Minimum Temperature and the Resolution. It is calculated using the formula:

Tmax = TMin + (Resolution * 253)

As you change the minimum temperature, resolution , or logger units, the maximum temperature is calculated and displayed.

Logger Units

This parameter determines the units (Celsius or Fahrenheit) used to set the Minimum Temperature and Resolution parameters.

Don't confuse the display units with the Mon-T Logger Units. The Mon-T Logger Units determine what units are used when programming the Mon-T - specific parameters (Minimum Temperature, and Resolution). The display units determine how temperatures are displayed in the Temprecord program

When a Mon--T logger is read, the display units are set to the Mon-T programmed logger units. I.e. if you program a logger in Fahrenheit units and read the logger with Temprecord set to display temperatures in Celsius, the display units will change to Fahrenheit after you read the logger's temperature data.

Also, when parameters are updated to a Mon-T logger (or to a G4 LCD logger), the temperature display units are set to the units that were programmed into the logger.

Warnings

Temprecord will warn you if you attempt to set the upper or lower limits outside the Minimum and Maximum Temperatures as defined above.

When the Mon-T logger is recording temperatures outside the logging range, the temperature actually recorded will be limited to the minimum or maximum temperature specified. This has implications for calculated statistics. It is important to make sure the range between the Minimum and Maximum Temperatures is greater than the expected temperature range.

These settings can only be adjusted if the option Show Mon-T - specific settings is enabled. If this option is not enabled, the fields for Minimum Temperature, resolution, and Logger Units do not appear and the logger temperature range and resolution are displayed in their place.
