What are the safety precautions in the use of the resistance acquisition instrument?
Publish Time: 2024-10-09
The safety precautions in the use of resistance acquisition instrument (or resistance tester) can be summarized as follows based on the description of professional information:
I. Equipment preparation and inspection
Power-off check:
Before using the resistance acquisition instrument, first make sure that the circuit is in a power-off state to prevent injury caused by electric shock.
Check whether the power supply and measuring lead of the resistance acquisition instrument are intact to ensure that the equipment is in normal working condition.
Measurement range selection:
Select the appropriate resistance range according to the approximate range of the resistance to be measured. If the resistance value is unknown, a larger range can be selected for measurement to avoid overload.
II. Connection and measurement operation
Correct wiring:
Connect the two probes of the resistance acquisition instrument to both ends of the circuit to be tested, and ensure that the probes are firmly connected to the circuit without looseness or poor contact.
Attention shall be paid to the correctness and stability of circuit connection during wiring.
Avoid live operation:
Avoid contacting the probe with live parts to prevent short circuit and electric shock.
Make sure that the circuit is de-energized when connecting and disconnecting the measurement leads.
III. Precautions during measurement
Avoid the influence of external forces:
In the process of measurement, attention should be paid to avoid the influence of external forces, such as severe vibration and vibration, in order to maintain the stability of the measured object.
Accurate reading:
When the resistance acquisition instrument is connected to the circuit and the appropriate measurement range is selected, read the display value on the resistance acquisition instrument and record the measurement results for subsequent reference.
IV. Operation after test
Disconnect:
After the measurement is completed, disconnect the circuit and turn off the resistance acquisition instrument to avoid unnecessary energy consumption.
Device reset:
Reset the resistance acquisition instrument to the initial state, and then remove the wiring. When removing wiring, be careful not to damage the equipment or wiring.
V. Equipment storage and maintenance
Storage environment:
The resistance acquisition instrument should be stored in a dry and ventilated environment to avoid high temperature and humid conditions, so as to ensure the normal operation of the instrument and prolong its service life.
Periodic calibration:
In order to ensure the accuracy of the measurement results, it is recommended to calibrate the resistance acquisition instrument regularly. The calibration interval depends on the frequency of use and the environmental conditions.
Cleaning and maintenance:
Keep the probe and measuring contact of the resistance acquisition instrument clean and avoid contact with contaminants to ensure the accuracy of the measurement results.
Maintain and clean resistance acquisition instrument regularly, and keep the appearance and internal components of the instrument in good condition.
VI. Other Precautions
Professional operation:
The operation of the resistance acquisition instrument shall be carried out by professionals or trained personnel to ensure the accuracy and safety of the measurement.
Follow the instructions:
When using the resistance acquisition instrument, be sure to follow the instructions in the instruction manual to avoid equipment damage or inaccurate measurement results caused by misoperation.
To sum up, the safety precautions in the use of resistance acquisition instruments cover equipment preparation, connection and measurement operation, measurement process, operation after test completion, equipment storage and maintenance, and other aspects. Following these precautions ensures the accuracy of the measurements and the safe operation of the equipment.
