How to use and precautions for electronic building thermometers
1. Electronic building thermometer got the temperature of engineering materials
The use of electronic construction thermometer to measure the temperature of engineering materials, concrete mix, mortar mix and liquid, etc., the use of temperature probe, the specific practice is to insert the plug of the temperature probe into the socket of the host computer, press the power switch, and then hold the probe handle, the probe will be inserted into the thing you want to measure, about 1 minute or so in the host computer to read the data, each time after the probe will be wiped clean.
2 electronic construction thermometer to measure the temperature of mass concrete
Construction temperature measurement programme to determine the number and depth of temperature measurement in accordance with the selection of the appropriate specifications of the temperature measurement line to carry out measurements, for example; the actual depth of the temperature measurement point 0.2m-0.3m, can choose the specification of the temperature measurement line 0.5m; the actual depth of the temperature measurement point 2.5m-2.8m, the specification can be selected for the temperature measurement line of 3m, and so on. Pre-embedded rebar can be used as a support, the temperature measurement line in accordance with the longitudinal temperature point distance tied to the support, temperature measurement line temperature-sensitive element in the temperature measurement point location shall not be in direct contact with the rebar, in the pouring of concrete, the tied temperature measurement line of the rebar into the concrete, the plug stays outside and covered with plastic tape to avoid moisture and keep clean. In order to facilitate the operation, stay outside the length of the wire greater than 20cm temperature measurement, press the host power switch will be inserted into the host temperature measurement line plug socket, the host display can show the corresponding temperature measurement point temperature
3. Electronic building thermometer to measure the temperature of winter construction concrete
Winter construction temperature measurement programme is determined, according to the requirements of the reserved temperature measurement holes, placed in each hole, a temperature measurement line, the temperature measurement line plug to stay outside the hole with a plastic tape cover, to avoid moisture, keep clean. Temperature measurement, press the host power switch, the temperature measurement line into the host socket host display can show the temperature of the corresponding temperature measurement point. After the end of each stage of temperature measurement, the temperature measuring line will be stored for the next time in the use. Temperature measurement line will also be buried in the concrete for one-time use.
4. The use of electronic building thermometer night lighting function
At night or in the dark environment, press the host lighting switch, the LCD display can emit a light green background light, so that the readings are clear and eye-catching.
5. Electronic building thermometer battery replacement screen
When the host LCD display appears battery symbol or can not be normal power on, generally due to insufficient battery voltage, need to change the new battery replacement battery replacement method; the host behind the battery compartment cover downward push, open the battery compartment cover will be removed from the old batteries, fasten the new batteries, and then restore the battery compartment cover to the original position.
Electronic building thermometer precautions;
1. When the host is not connected to the temperature probe or temperature measurement line, the display shows -1 as the ready-to-work status.
2. Do not use excessive force in the operation of the electronic building thermometer, and hold the plug steady when inserting it into or pulling it out of the socket of the host computer.
3. Plugs and sockets of the host should avoid moisture and keep clean. If the water is inadvertently damp, please wipe clean and dry before use, so as to avoid inaccurate temperature measurement results.
4. The use of electronic building thermometer should be turned off in a timely manner after the completion of the long-term use of the battery should be removed to avoid damage to the instrument.
5. Do not open the back cover of the host, when you need to repair or calibration, please send back to the manufacturer or agent for repair or calibration.
