Laserliner ThermoMaster Plus Contact Thermometer

INTRODUCTION

**!** Completely read through the operating instructions, the „Warranty and Additional Information“ booklet as well as the latest information under the internet link at the end of these instructions. Follow the instructions they contain. This document must be kept in a safe place and passed on together with the device

Function / Application

The digital thermometer is used to measure temperature and temperature differences with the aid of
exchangeable type K/J/T/E thermcouples/sensors. The digital thermometer is predominantly used for temperature measurement in laboratories and in industrial applications. With the aid of the MAX function it is possible to determine limit temperature infringements in extended series of measurements.

General safety instructions

The device must only be used in accordance with its intended purpose and within the scope of the specifications.
Not suitable for potentially explosive areas or medical diagnoses.
The measuring tools and accessories are not toys. Keep out of reach of children.
Modifications or changes to the device are not permitted, this will otherwise invalidate the approval and safety specifications.
Do not expose the device to mechanical stress, extreme temperatures, moisture or significant vibration.
Do not power the thermocouple (K-type) with an external voltage.
The device must no longer be used if one or more of its functions fail or the battery charge is weak.
Please ensure compliance with the safety regulations set out by local and national authorities with regard to the correct and proper use of the device.

Safety instructions

Dealing with electromagnetic radiation

The measuring device complies with electromagnetic compatibility regulations and limits in accordance with the EMC Directive 2014/30/EU which is covered by the Radio Equipment Directive 2014/53/EU.
Local operating restrictions – for example, in hospitals, aircraft, petrol stations or in the vicinity of people with pacemakers – may apply. Electronic devices can potentially cause hazards or interference or be subject to hazards or interference.
The measuring accuracy may be affected when working close to high voltages or high electromagnetic alternating fields.

Safety instructions

Dealing with RF radiation

The measuring device is equipped with a wireless interface.
The measuring device complies with electromagnetic compatibility and wireless radiation regulations and limits in accordance with the RED 2014/53/EU.
Umarex GmbH & Co. KG hereby declares that the ThermoMaster Plus radio-based system complies with the requirements and other stipulations of the European Radio Equipment Directive 2014/53/EU (RED).

General instructions

If the thermometer is subject to large fluctuations in the ambient temperature, after the temperature has stabilised, wait 20 minutes before performing a measurement.
Always ensure adequate thermal coupling at the measuring point in order to avoid measuring errors caused by temperature loss.
Please note that all thermometers with a contact sensor influence the measurement and their thermal capacity can reduce the actual temperature. More thermal energy should therefore be applied to the thermocouple than it can dissipate.
Four lines will appear in line A if no thermocouple is connected.
Lo or Hi will be displayed if the measured temperature is outside the measuring range.
Only use the correct type of thermocouple (type K, J, T or E) and make sure that the device is set to the corresponding type. The wrong type can cause significant measuring errors.
In addition to being subject to ageing, a thermocouple is also greatly depending on the operating conditions and should therefore be checked regularly.
High pressure or mechanical deformation can change the grid structure and therefore have an influence on the thermoelectric voltage output.
The thermometer and thermocouples have different measuring ranges and accuracies and therefore need to be considered separately.

Inserting batteries

Open the battery compartment and insert batteries according to the symbols. Be sure to pay attention to polarity

Connecting thermocouples

**!** Pay attention to the polarity information on the ! thermocouple as well as on the device connection

The HOLD function shows the last measurement or measured value in the display

Temperature measurement (T1, T2)

With one thermocoupl

When measuring with one thermocouple, the measured value of the connected thermocouple T1 or T2 is shown in line A. The display shows whether T1 or T2 is connected.
With two thermocouples

The measured value of thermocouple T1 is shown in line A and the measured value of thermocouple T2 in line B.

Show MAX / MIN / AVG / T2-T1

With one thermocouple

! TIP: When line A is set to MAX and line B to MIN a direct MAX/MIN comparison can be made with one thermocouple.

With two thermocouples (Example T1)

**A** Press button A to show the MAX, MIN, AVG values of thermocouple T1 as well as the difference T2-T1.
**B** Press button B to show the MAX, MIN, AVG values of thermocouple T2 as well as the difference T1-T2.

Memory function / call up memory

The device has 10 storage locations.

The current measured value display is stored at the next free memory location by short-pressing the LOG button. An acoustic signals confirms successful storage
The measured value memory is called up by long-pressing the LOG button. The measured value view and storage location are shown alternately.

The measured value memory is exited by short-pressing the ESC button.

Auto power off

Temperature alarm

By activating the „Temperature alarm“ function, deviations from the required temperature range are indicated by the (f) symbol on the display flashing and a two-stage (10 minutes / 3 seconds) acoustic signal. The temperature alarm can be cancelled by pressing the ESC button and is set to „OFF“ in the menu.
You can set the temperature range, see section 10 „Temperature alarm LO“ and section 11 „Temperature alarm HI“.

Clearing memory

**!** he display flashes while clearing the memory. A signal sounds when the memory is cleared.

Restoring factory setting

The display flashes while restoring the factory setting. A signal sounds when the factory setting is restored.
**!** The clearing procedure cannot be stopped or cancelled.

Standard view

The display is reset to the standard view (view after switching on with thermocouple connected) by unplugging and reconnecting a thermocouple. The standard view can also be set by pressing the ESC button.

Data transfer

The device features a Bluetooth® function that enables wireless data transfer to mobile devices
with a Bluetooth® interface (such as a smartphone or tablet).
The system prerequisites for a Bluetooth® connection are specified at http://laserliner.com/info an=ble The device can set up a Bluetooth® connection with Bluetooth 4.0 compatible devices.
The range is set to a maximum distance of 10 m from the terminal device and greatly depends on the ambient conditions such as the thickness and composition of walls, sources of interference as well as the transmit / receive properties of the terminal device.
Once it has been activated, Bluetooth®* remains switched on indefinitely as the radio system is designed with exceptionally low power consumption.
A mobile device can link up to the active measuring device via an app

Application (app)

An app is required to use the Bluetooth®* function.
You can download the app from the corresponding stores for the specific type of terminal device

**!** Make sure that the Bluetooth®* interface of the mobile device is activated

After starting the app and activating the Bluetooth®* function, a connection can be set up between a mobile device and the measuring device. If the app detects several active measuring devices, select the matching device

This measuring device can be connected automatically the next time it is switched on.

Information on maintenance and care

Clean all components with a damp cloth and do not use cleaning agents, scouring agents and solvents.
Remove the battery pack before storing for longer periods. Store the device in a clean and dry place. Do not touch the lens.

Calibration

The meter needs to be calibrated and tested on a regular basis to ensure it produces accurate
measurement results. We recommend carrying out calibration once a year.
