4. OPERATION INSTRUCTIONS

4.1 Power-Up

Press the “ ” key to turn ON the thermometer and Press and hold “ ” buttons for 3 seconds

to OFF.

4.2 Connection the Temperature Pprobe

For measurement, plug the temperature probe into the input connectors.

4.3 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 button and vice versa to Celsius and change

the default scale.

4.4 Data-Hold Operation

The user may hold the present reading and keep it on the display by pressing the button.

When the hold data is no longer needed, one may release the data-hold operation by pressing

button again.

When the meter is under Data Hold operation, the , and button are disabled.

4.5 Back light Operation:

The meter will turn the back light off if there is no push button for 30 seconds.

4.6 Relative Operation:

When one presses the button, the meter will memorize the present reading and the difference

between the new reading and the memorized data will be shown on the display. Press the

button again to exit the Relative operation.

4.7 Record Operation:

Starting and Stopping Logging Setup, memory clear, and PC communications are inaccessible

during logging.

Set the logging interval. (See “Changing the Logging Interval.”)

Press button to start logging. The display shows “REC”.

Press button again to stop logging.

4.8 MAX/MIN Operation:

When one presses the button the meter will enter the MAXMIN mode. Under this mode the

maximum value, minimum value is kept in the memory simultaneously and updated with every new

data.

When the MAX symbol is displayed, the Maximum reading is shown on the display.

RTD THERMOMETER

Press button again, then the MIN symbol is on the display and also the minimum reading.

Press button again, MAX and MIN will blink together. This means that all these data is

updated in the memory and the reading is the present temperature.

One may press to circulate the display mode among these options.

When the meter is under MAXMIN operation, and button is disabled.

To exit the MAX/MIN mode, one may press and hold button for two seconds.

4.9 Auto Power Off:

By default, when the meter is powered on, it is under auto power off mode. The meter will power

successive beeps to indicate that the auto power off is disabled.

4.10 Low Battery Condition:

The temperature meter low battery indication shows as follows:

Low battery. Replace the batteries.

5. TEMPERATURE MEASUREMENT

5.1 Correct Measurement Method:

The temperature sensor is located at the end

of the metal sheath of the sheath type

TEMPERATURE PROBE. To accurately test

internal temperature insert the probe into the

item you want to measure to a distance of

at least 15 times the diameter of the sheath.

5.2 Connector Configuration:

RTD THERMOMETER

6. SETTING THE TIME
