High-speed static strain gauge troubleshooting

High-speed static strain gauges are mainly used for static and dynamic stress analysis, and dynamic and static load strength studies to measure dynamic and static stress-strain measurements at any point in the structure and material. Juhang Technology summarizes the faults and troubleshooting of high-speed static strain gauges.

1. After turning on the power, there is no display;

Checking steps:

1) Check if the fuse is disconnected.

2) Is the power plug disconnected?

2. The instrument is in the measurement state, but the measurement bridge cannot be balanced.

Checking steps:

1) Check that the measurement bridge connection is correct.

2) Whether the strain gauge is short-circuited or disconnected, and whether the strain gauge resistance error exceeds the specified range.

3) Check if the bridge pressure is normal.

4) Check the amplifier, A/D display and other working conditions are normal.

3. The instrument display shows continuous shifting.

Checking steps:

1) Is the bridge pressure normal?

2) Whether the power supply of the amplifier is normal, and whether the amplifier circuit works normally and stably.
