Frequently Asked Questions - T 318 PCE Instruments

How do I change the temperature scale from °C to °F?

Press the °C/°F button to toggle between Celsius and Fahrenheit. The default scale is °C.

How do I hold the current reading on the display?

Press the HOLD button to freeze the display. Press it again to release the hold. Note that during hold, relative mode and some functions are disabled.

How do I use the MAX/MIN/AVG function?

Press the MAX MIN button to enter MAX/MIN/AVG mode. The meter stores the maximum, minimum, and average of the latest 8 readings. Repeated presses cycle through MAX, MIN, AVG, and live readings. Press and hold for 2 seconds to exit.

How do I change the platinum RTD type (Pt100, Pt500, Pt1000)?

Press and hold Power + Light buttons for 2 seconds to enter setup. Press HOLD to enter Pt type selection, then press MAX to cycle through Pt100, Pt500, Pt1000. Confirm with °C/°F.

How do I replace the batteries?

Remove the back cover screw, replace with 3 x AAA alkaline batteries observing polarity. Ensure the rubber gasket is properly seated before closing to maintain IP67 water resistance.

How do I calibrate the thermometer at 0°C?

Enter setup mode (hold Power + Light). Press ΔREL to enter calibration mode. Connect a known 0°C source, then press ΔREL to confirm. Press °C/°F to accept the offset.

How do I disable Auto Power Off?

Press and hold the HOLD button while turning the meter on. You will hear two successive beeps indicating that auto power off is disabled.

What is the water resistance rating of the PCE-T 318?

The thermometer has an IP67 rating, meaning it is dust-tight and can be immersed in water up to 1 meter for 30 minutes, provided the battery cover is properly sealed.

What type of probe is included and what are its specifications?

It comes with a piercing type temperature probe: Pt100 (4-wire), class A accuracy (±0.15°C ±0.002t), range -100 to 400°C, sheath diameter approx. 3.2 mm, length 120 mm, cable length 1100 mm, IP67.

5.2 Connection of the temperature probe

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

6 Selecting the Temperature Scale

When the meter was first power 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.

7 Data-Hold Operation

The user may hold the present reading and keep it on the display by pressing the "HOLD" button. When the hold 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 “ΔREL”, (AVG MAX 100) and “°C/°F” button are disabled.

8 Back light Operation

Press the "Back Light" button will turn back light on and Press it once again will turn off. The meter will turn back light off if there is no push "Back Light" button for 10 seconds.

9 Relative Operation

When one press the “ΔREL” 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 “ΔREL” button again to exit the Relative operation.

10 MAX/MIN/AVG Operation

When you press the "MAX MIN" button the meter will enter the MAX/MIN/AVG mode. Under this mode the maximum value, minimum value and average value of latest 8 data is kept in the memory simultaneously and updated with every new data.

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

Press "MAX MIN" again, then the NIN symbol is on the display and also the minimum reading.

Press "MAX MIN" again, the AVG symbol is on the display and also the average reading.

Press “MAX MIN” again, MAX, MIN and AVG will blink together. This means that all these 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, “ REL” and “ ^ C/ ^ F” are disabled.

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

11 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.

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.

12 Low Battery Condition

The temperature meter incorporates visual low battery indication as follows:

	Battery OK, measurements are possible.
	Battery Low, battery needs to be replaced, measurements are still possible.
	Battery exhausted, the battery need to replaced with new one(size AAA, 1.5V x 3).

13 Temperature Measurement

13.1 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 at least 15 times the diameter of the sheath.

18 Maintenance

18.1 Replacing the Batteries

(1) Remove back cover screw to remove cover. Verify polarity and install new LR03(AAA size) alkaline batteries.
(2) Fit cover properly and tighten screw.

The unit's back cover is fitted with rubber rings. After replacing the battery, check that the rubber rings are properly seated before reinstalling the back cover. Improper seating of the rubber rings will compromise the unit's water-resistant structure, and possibly result in damage to the equipment.
