Frequently Asked Questions - PL125T2 VOLTCRAFT

How to install the Voltsoft software provided with the thermometer?

Insert the CD into the drive. The installation starts automatically; otherwise open 'setup.exe' on the CD. Follow the instructions, choosing French if available. Accept the license, choose the destination folder, and finish. The software allows you to retrieve recorded data.

How to replace the batteries of the PL125T2 thermometer?

Unscrew the screw of the battery compartment cover with a Phillips screwdriver. Insert three AAA batteries respecting the indicated polarity (+/-). Close the cover. Replace the batteries when the battery icon appears on the screen.

How to freeze the displayed measurement (HOLD function)?

Press the HOLD button (▼) to freeze the current measurement. The text 'HOLD' appears at the top of the screen. Press HOLD again to return to real-time display.

How to set the date and time on the device?

Hold down the SET button to enter setup mode (SETUP). Use ▲ T1·T2 or ▼ HOLD to navigate to the parameter 'tiE' (time). Press REC ENTER to access the settings. The top four digits are the year, the ones below are month and day, and at the bottom is the time (HH:MM). Adjust with ▲/▼ and confirm with SET.

How to clear the internal memory (delete records)?

In SETUP mode, select the parameter 'CLR1' (clear memory) with ▲/▼. Press REC ENTER. Choose 'YES' to clear the memory without backup. Note: This action is irreversible.

What to do if the screen displays '----' (four dashes) for a channel?

This means no temperature sensor is connected to that channel (T1 or T2). Connect a compatible thermocouple to the corresponding port. If the sensor is damaged, replace it.

How to change the display unit (°C, °F, K)?

Press the UNITS button to toggle between Celsius (°C), Fahrenheit (°F), and Kelvin (K). The selected unit is displayed on the screen.

How to use the MAX, MIN, and AVERAGE functions?

Press the ◀ MAX MIN button to enter the mode. A single press displays MAX, a second press MIN, a third press AVG (average). Use ▲ T1·T2 to toggle between T1 and T2 or the difference. Hold MAX/MIN for 2 seconds to return to normal mode.

How to connect the thermometer to a computer?

Connect the provided USB cable (mini USB on the device, standard USB on the PC). Launch the 'Multiple Data Logger' software. Refer to the software help for data transfer instructions.

What safety instructions must be followed?

Do not use the device to measure the temperature of body parts or conductive parts (risk of electric shock). Keep it out of reach of children. Avoid moisture, flammable gases, extreme temperatures. Respect battery polarities. If in doubt, consult a specialist.

2. INTENDED USE

This product is designed for temperature measurement and is especially suitable for use in laboratories and industrial areas. Temperature measurement is done via one or two temperature sensor(s). Temperature can be measured with temperature sensors of type K and J. Measured values can be frozen on the screen. The product can display the minimum, maximum and average value of a particular measurement process. Temperature can be displayed in °C (Celsius), °F (Fahrenheit) or K (Kelvin). The product features an auto-off and a backlight function. The product is capable of providing two measurements. The product can also calculate the difference between the measured values T1 and T2 and provide the maximum, minimum and average difference of the measured values T1 and T2. Power is supplied by three AAA batteries. Use only in a dry indoor environment.

Measurements should not be carried out under unfavourable ambient conditions. Adverse conditions are:

• Moisture or excessive humidity
• Dust and flammable gases, vapours or solvents.
• Thunderstorms or similar conditions such as strong electrostatic fields, etc.

Unauthorised conversion and/or modification of the device are inadmissible because of safety and approval reasons (CE). Any usage other than described above is not permitted and can damage the product and lead to associated risks such as short-circuit, fire, electric shock, etc. Please read the operating instructions thoroughly and keep them for further reference.

9. OPERATION

• Do not measure the temperature of live parts or leads, as touching them might cause a potentially lethal electric shock. Also, the thermometer and sensor could be damaged.
• The sensor included with delivery can only be used for measurements in dry environments and on surfaces with a temperature of >-20 °C and <+250 °C. It is not suitable for use in humid environments or to measure the temperature of fluids.
• The accuracy is only assured when the thermometer is operated at a temperature range of +18 °C to +28 °C (excluding the temperature sensor).
• The thermometer (excluding the temperature sensor) must not be used outside the operating temperature range. Please note the specifications on operating temperature in the Technical Data section.
• You can utilize the entire measurement range of the thermometer with optionally available temperature sensors.

Basic functions

1. Connect the temperature sensor to port T1/T2 on the top of the device. Only one direction is possible. Please note the polarity labelling on the temperature sensors' plug and on the side of the port.
