Description

The Greenlee TML-30 is a hand-held testing device intended to measure temperature (Celsius and Fahrenheit). It can accommodate one or two K-type or J-type thermocouples, purchased separately, and has a built-in memory for logging measured data.

Once data is collected in the meter, it can be downloaded to a PC (software and cable included) where the data can be viewed in a list or a graph, saved to a file, and exported to a spreadsheet application such as Microsoft Excel®. While the meter is connected to a PC, users can view real-time readings and record the data on the PC.

Safety

Meter Operation

Turning the Meter On and Off

1. Connect temperature probe(s) to the meter.

2. Press ON/HOLD/OFF to turn the meter on. The meter performs a self-test. “tESt” indicates

that the test is in progress. “PASS” indicates that the meter has passed the self-test.

3. To turn the meter off, press and hold ON/HOLD/OFF. The display counts down (3, 2, 1)

and the meter turns off.

4. Release the button.

Holding a Reading

After turning the meter on, readings can be stopped and held. During this time no further readings are recorded. To hold a reading, press ON/HOLD/OFF. To release the function, press again.

Measuring Maximum and Minimum Temperatures

The TML-30 temporarily stores the maximum and minimum temperature readings of the primary thermocouple and averages the last ten readings. It also indicates the elapsed time at which the maximum and minimum readings were taken and how long the mode has been running. The information in this mode is not recorded in the database.

NOTE: All other functions are disabled while in this mode, except ON/HOLD/OFF.

1. Press T1 / T2 / T1-T2 to select the primary thermocouple.

2. Press MAX/MIN/AVG to start the clock and to record the maximum temperature.

“MAX” appears on the display. The maximum temperature appears in the display and updates as new values come in. The clock indicates the time into the test the last update occurred.

3. Press MAX/MIN/AVG to display the minimum value recorded and the time it was taken.

4. Press MAX/MIN/AVG to display the average of the last ten samples. The clock shows how

much time has elapsed since the test began.

5. Press MAX/MIN/AVG again to show the normal display. The maximum/minimum feature

continues to run, indicated by on the display.

6. Press MAX/MIN/AVG to cycle through the readings. To clear the maximum/minimum

feature, press and hold MAX/MIN/AVG until disappears.

Meter Operation (cont’d)

Using the Relative Mode

This mode calculates the difference between two measurements of the primary thermocouple. While taking a measurement, press REL to set the display to zero. The ∆ icon appears on the display. Take the second measurement. The value on the display is the difference between the two measurements. Press again to exit this mode.

Changing the Thermocouple type

The TML-30 defaults to a K-type thermocouple each time it is turned on. To change to J-type, with the meter turned off, press and hold REL / J while turning the meter on. “J” appears on the display. The “K”, which normally appears in the upper left corner to indicate a K-type thermocouple, does not appear.

Selecting the Primary Thermocouple

T1 is the default primary thermocouple and is displayed in the center of the display. T2 is the default secondary thermocouple and is shown in the lower right. To make T2 primary, press T1 / T2 / T1-T2 until the display shows “T2”. T1 becomes secondary. Press again to enter the Difference mode (see below). The secondary display alternately displays “T1” and “T2”. Press again to return T1 as primary.

Determining the Difference Between the Two Thermocouples

The T1-T2 mode calculates the difference between T1 and T2. Press T1 / T2 / T1-T2 until the display shows “T1-T2” to enter the Difference mode. The difference appears in the primary display and is constantly updated as the readings change. Press the button again to return to the normal setting.

Recording Measurements to Memory

Recordings are held in memory as “sets” so that they can be downloaded to a PC using the Temperature software. Each time you start recording, a set is created in the database. You can record one sample or record samples continuously. “FULL” on the display indicates that the memory is full.

The sample rate (Interval) determines how often the reading is recorded to the database. See Setting the Recording Interval.

1. To record one sample, press and release REC/ERASE. “REC” flashes once on the display.

2. To record continuously, press and hold REC/ERASE for three seconds. “REC” flashes every second on the display.

3. To stop recording, press the button again.

Erasing the Memory

With the meter off, press and hold REC/ERASE while turning the meter on. “dEL” appears on the display to indicate that the measurements have been deleted from the memory. The meter then goes through its self-test.

Using Lists

Lists can be accessed from the DISPLAY menu on the THERMOMETER dialog box to view real-time data and by opening a saved file through the FILE menu. They are also generated when data in the meter is selected. Essentially, the contents of lists appear and function alike. However, the menu bar commands have minor differences, depending on where they are accessed.

List Features

• FILE (real-time) Point to FILE and click one of the following:

CONTINUE Click to resume recording data. Dimmed when the data is being recorded. PAUSE Click to stop recording incoming data. Dimmed when the recording is paused. GRAPH Click to display the real-time data in a graph. See Using Graphs. PRINT Click to print the data.

Using Graphs

Graphs are accessed from the THERMOMETER dialog box to display real-time data or from the saved data list to display the contents of the list. The menu commands on the graphs are the same. However, the titles of the menu commands are slightly different. For example, when you are using a real-time graph and you point to DISPLAY, the commands T1, T2, or T1-T2 include the term (DISABLE) or (ENABLE). These terms do not appear on the saved data graph.

Readings in the graph are based on the sampling rate. The graph can be minimized and restored.

Using Thermometer for Real-time Recording

Setting the Sampling Time for Real-time Recording

The TML-30 takes a reading every second. The sampling rate is the rate that those readings are logged to the file. For example, even though the meter takes a reading every second, you may decide to log a sample every 30 seconds. Setting the sample rate using the following procedure sets the sample rate for real-time data and does not affect the sample rate in the meter. The rate is set in seconds.

1. On the THERMOMETER dialog box DISPLAY menu, click SAMPLE RATE. The Input Sampling Time dialog box appears.

2. Type in a new number. The maximum is 65 seconds.

3. Click OK. Data collected is sampled at the new rate.

Page 20

Recording Real-time data into the PC

Thermometer allows you to record readings directly into the PC from the meter without using up memory in the meter. This is especially useful when you need more memory storage for longer recording sessions. It also allows you to remotely monitor temperatures. When recording from the PC, the buttons on the TML-30 continue to function normally; however the word “Record” does not appear on the display. Before you begin, you must assign a file name.

1. Open a new file by clicking SAVE AS on the FILE menu. A Windows Save dialog box opens.

2. Enter a file name, using eight characters or less and add a .dat extension.

3. Select a location for the file.

4. Click OK.

5. On the FILE menu, click START RECORDING. A message appears at the bottom of the dialog box that shows the directory path and file name. The word “RECORDING” and the record number appear below the file name. The “display” at the top of the dialog box shows real-time data as it comes from the meter.

6. To quit recording data, on the FILE menu, click STOP RECORDING.

7. Click SAVE AS. The Save As dialog box appears.

8. Save the data under the same file name and location.

9. Click OK.
