3. OPERATION
3.1 Safety
The LDT 2000 temperature meter is a device designed for laboratory, indoor use. It is
powered from 85 to 250V line, therefore the user should work with respect to all precau-
tions related to operating with mains powered equipment. The mains socket should always
have working grounding path!
3.2 Preparation to work
1. Connect one or two (as needed) probes to the sockets on the thermometer’s front panel.
Please keep in mind that each channel has its own calibration coefficients and probe’s
plug must be placed in proper, signed socket. A mistake will result in wrong temperature
readings
2. Connect the instrument to the power line
3. Turn on the instrument by pressing POWER switch
4. Read the messages displayed by the instrument (chapter 3.3)
5. Wait until self calibration sequence reaches 100%
6. The thermometer is now ready to stand- alone operation
