Frequently Asked Questions - TC 34N PCE Instruments

How do I change the measurement unit from °C to °F?

Press and hold the 'HOLD' button for 3 seconds to toggle between °C and °F. The current unit is displayed on the screen.

What type of battery does the TC 34N use and how do I replace it?

It uses a standard 9V battery (6F22). To replace, slide off the battery compartment cover on the back, disconnect the old battery, and connect a new one observing polarity.

Can I use the thermometer for liquids?

Yes, as long as the probe is designed for immersion. The included type K thermocouple is suitable for liquids. Ensure the probe handle remains dry.

How accurate is the TC 34N?

The accuracy is ±0.5°C in the range -10°C to +150°C and ±1°C outside that range. For best results, allow the probe to stabilize.

What does the 'HOLD' function do?

Pressing 'HOLD' freezes the current reading on the display. Press again to release and continue live measurement.

How do I access the min/max readings?

Press the 'MIN/MAX' button to cycle through the minimum, maximum, and current readings. The display will show 'MIN' or 'MAX' accordingly.

What should I do if the display shows 'OL' or 'ERR'?

'OL' indicates the temperature is outside the measurement range. 'ERR' may indicate a faulty probe or sensor connection. Check the probe and ensure it is properly connected.

How do I clean the thermometer?

Wipe the device with a soft, damp cloth. Do not use solvents or immerse in water. Dry thoroughly before storage.

Is the TC 34N suitable for food safety applications?

The thermometer can measure food temperatures, but ensure the probe is cleaned and sanitized between uses. The device itself is not waterproof.

5 Switching the meter on and off

To switch the meter on and off, press and hold the key for about three seconds. After switching on, the measurement starts immediately.

Note: After the meter has been switched on, the protective cap must be opened. Close the protective cap as soon as you switch off the meter. Before the measurement, the meter must have acclimatised.

5.1 Thermal image

The colours shown in the thermal image are not specific to a temperature. They are relative to the coldest and hottest temperature measured. The coldest and hottest spot are indicated by a red and a green dot on the display. The position for the temperature measurement in the centre of the thermal image cannot be changed.

5.2 Picture-in-picture function

To use the picture-in-picture function, use the ▼ and ▶ keys during the measurement. 5 levels are available.

5.3 Take a picture

To take a picture, use the trigger key. You will then be asked if you want to save the image. Select "Yes" or "No" with the navigation keys and confirm your entry with the "SELECT KEY."

5.3.1 Transferring images to a computer

To transfer the saved images to a computer, connect the measuring device to a computer via the USB-C interface and switch it on. The meter is recognised as a mass data storage device. After the meter has been recognised by the computer, the images can be transferred directly without any software.

5.4 Lowest / highest measured value and time

To additionally display the lowest and highest measured value and the time, press the key during the measurement. The highest and lowest readings are shown with the time at the bottom of the display. Press the key again to hide this view.

6 Menu

To make settings, press the key. Use the navigation keys to select functions and change parameters. Use the key to open menu items and save settings.

6.1 Picture in-picture adjustment

If the real image and the thermal image are not on top of each other, this can be changed via the item "Image registration" in the menu. The image can now be moved with the navigation keys.

Confirm the entry with the key.

When a setting is made, it is automatically closed after six seconds.

Note: Set the picture-in-picture function in advance so that you can see both pictures equally well.

6.2 View images

To view the saved images, go to the icon in the menu. From there, the individual images can be accessed.

If an image is opened, you can use the and keys to jump to the next and previous image. Press the key to return to the menu. Press the key to resume the measurement.

The currently opened image can be deleted with the - image. Before deleting, you will be asked whether you really want to delete the image. Select "Yes" or "No" with the navigation keys and confirm your entry with the SELECT key.

6.3 Change colour palette

To change the colour palette, enter the menu and click on the icon. From there, any colour palette can be selected.

There are five different palettes to choose from:

Thermal imaging of a lit incandescent lamp showing heat distribution (no text or symbols on the lamp itself)

Thermal imaging of a cylindrical object with heat distribution visualization (no text or symbols on the object itself)

Close-up of a lit fuse tip against a dark background, no visible text or symbols

Close-up of a black pen tip with a cross mark, shown in a photo editing interface (no readable text or symbols on the object itself)

6.4 Set emissivity

To set the emissivity, enter the menu and click on the ε icon. From there, different emissivities can be set. For faster setting, four fixed emissivities are pre-set. If necessary, a specific value can also be set.

6.4.1 Example emissivities chart

The emissivity describes the energy emission behaviour of materials. Most (90 % of typical applications) organic materials and painted or oxidised surfaces have an emissivity of 0.95 (default setting in the meter).

If you measure shiny or polished metallic surfaces, this will result in a loss of accuracy. If possible, cover the surface to be measured with temperature-resistant black tape or a thin layer of black paint. Wait a little while until the tape or paint layer has reached the same temperature as the material underneath. Now measure the temperature on the tape or painted surface.

Material	Heat emissivity	Material	Heat emissivity
Asphalt	0.90 ... 0.98	Fabric (black)	0.98
Concrete	0.94	Human skin	0.98
Cement	0.96	Leather	0.75 ... 0.80
Sand	0.90	Charcoal (powder)	0.96
Soil	0.92 ... 0.96	Lacquer	0.80 ... 0.95
Water	0.92 ... 0.96	Lacquer (matt)	0.97
Ice cream	0.96 ... 0.98	Rubber (black)	0.94
Snow	0.83	Plastics	0.85 ... 0.95
Glass	0.90 ... 0.95	Wood	0.90
Ceramics	0.90 ... 0.94	Paper	0.70 ... 0.94
Marble	0.94	Chromium oxides	0.81
Plaster	0.80 ... 0.90	Copper oxides	0.78
Mortar	0.89 ... 0.91	Iron oxides	0.78 ... 0.82

Note: This chart is for guidance only.

8 Charging the battery

As soon as the battery indicator shows a flat battery, it must be charged so that the meter can continue to be used.

To charge the battery, connect the meter to a USB charging station via the USB-C interface. As soon as the meter is connected, this is indicated by the battery status display. A 5 V DC, 2 A power supply is recommended here. After charging, the battery lasts approx. 3 hours.

As soon as the display shows that the battery is fully charged, charging must be stopped.

Note: The battery must not be continuously connected to the charging station. This could damage the battery. If the meter will not be used for a longer period of time, the battery should be charged in between. At the latest after three months of inactivity, the battery should be charged for approx. 2 hours.

11 Disposal

For the disposal of batteries in the EU, the 2006/66/EC directive of the European Parliament applies. Due to the contained pollutants, batteries must not be disposed of as household waste. They must be given to collection points designed for that purpose.

In order to comply with the EU directive 2012/19/EU we take our devices back. We either re-use them or give them to a recycling company which disposes of the devices in line with law.

For countries outside the EU, batteries and devices should be disposed of in accordance with your local waste regulations.

If you have any questions, please contact PCE Instruments.
