5. Precautions for use and order:

1.The type and specification of the input signal of the instrument before use, and the

requirements of the installation control system shall be met in accordance with the

requirements of the installation control system.

2.Please contact the distributor or manufacturer according to the correct wiring drawings or instructions.

3, K type thermocouple, if you want to extend the sensor lead, please use

thermocouple compensation wire,using internal automatic compensation models,

compensation conductor should be directly to the instrument of the terminal,middle can’t

into conventional wire, otherwise it will produce error of measurement.

4.When receiving the Pt100 platinum resistance, when using the compensation wire, please use the same specification of low resistance wire,and the three-wire resistance value is as much as possible to avoid measurement errors.

5.If the instrument sensor is connected to the wrong line or the input signal is abnormal, the digital tube will display the fault code Err. Is the sensor damaged?

6.The instrument power line and the signal line should be separated from the large current transmission line to reduce the influence of the electromagnetic radiation on the

instrument. In case of unavoidable,please use the shielded wire as far as possible.

7.The instrument can be energized only when the wiring is correct, especially the power supply and output power line, which may damage the internal circuit of the instrument.

8, when ordering, please specify the instrument specific models (see the instruction

of "model meaning and expression" column) can also be note details of instrument

input signal types, specifications, measuring range, output method, instrument power

supply or other special technical requirements.

9.Accessories attached to the factory instrument:a set of mounting bracket,one copy, and one set of temperature and humidity sensors. If there is any abnormality in the use of instrument,please check the instruction manual or the after-sales service

hot-line email:cynthia-leung@qq.com for technical support

10.During the use of failure and unsealed, the manufacturer shall maintain free maintenance within one year.

Precautions when setting parameters:

1. When the meter is in a set state, if no keystroke is performed within 10 seconds, the meter will automatically exit the set state and return to the measurement and control operation state.

2. Press "SET" key to select the parameters, and click " " and" "key to change the value.

3. In the setting state, the long and holding " " and" "key can rapidly increase/decrease the value.

4.Under any parameter setting, press the "SET" key for about 3 seconds, and immediately exit the SET state and

return to the measurement control status.
