DIGITAL VETERINARY THERMOMETER

microlife VT 1831 Digital Veterinary Thermometer

Read the instructions carefully before using this device.

IMPORTANT SAFETY INSTRUCTIONS

Follow instructions for use. This document provides important product operation and safety information regarding this device. Please read this document thoroughly before using the device and keep it for future reference.
The thermometer is exclusively for the measurement of the animal body temperature.
The minimum measurement time until the signaling tone [beep] must be maintained without exception!
Ensure that children do not use this device unsupervised; some parts are small enough to be swallowed.
Do not use this device close to strong electromagnetic fields such as mobile telephones or radio installations. Keep a minimum distance of 3.3 m from such devices when using this device.
Protect the thermometer from hitting and striking!
Avoid ambient temperatures above 60 °C. NEVER boil the thermometer!
Use only the commercial disinfectants listed in the section «cleaning and disinfecting» to clean the thermometer. The thermometer must be intact when immersed in liquid disinfectant.
The manufacturer recommends verifying the accuracy by an authorized laboratory every 2 years.

WARNING: The measurement result given by this device is not a diagnosis! Do not rely on the measurement result only.
Batteries and electronic instruments must be disposed of in accordance with the locally applicable regulations, not with domestic waste.

TURNING ON THE THERMOMETER

To turn on the thermometer, push the ON/OFF button; a short signaling tone [beep] signals «thermometer ON». A display test is performed. All segments should be displayed. Then at an ambient temperature of less than 32 °C, «- – -» and a flashing «°C» appear at the upper right of the display. The thermometer is now ready for use.

FUNCTION TEST

The proper functioning of the thermometer is tested automatically each time it is turned on. If a malfunction is detected (measu rement inaccuracy), this is indicated by «ERR» on the display, and measurement becomes impossible. In this case, the thermometer must be replaced.

USING THE THERMOMETER

During a measurement, the current temperature is displayed continuously. The «°C» symbol flashes during this period of time. If the signal tone sounds (beep-beep-beep-beep 10 times) and the «°C» is no longer flashing, this means that the measured increase in temperature is now less than 0.1 °C in 8 seconds and that the thermometer is ready for reading.
To prolong the life of the battery, turn the thermometer off after use by pressing the operating button briefly. Otherwise, the thermometer will automatically turn off after about 10 minutes.

STORAGE OF MEASURED VALUES

If you hold the button down for more than 3 seconds when turning the thermometer on, the maximum temperature stored automatically at the last measurement will be displayed. At the same time, a small «M» for memory will appear at the right of the display. After 3 more seconds, this value will disappear and the thermometer will automatically turn off.

CLEANING AND DISINFECTING

The thermometer is 100 % waterproof and may be immersed in water or disinfectant solution for cleaning with no problem. Then wipe it off with a moist towel. Please use the following disinfectant for disinfecting, following the manufacturer’s instructions:
Note: Any other cleaning solution, dilution, or cleaning method can cause a malfunction of the thermometer! The thermometer must never be boiled!

MEASURING METHODS
In the anus (rectal)
