FAQ‑Digital Vibration Meter

Q1: What is the Digital Vibration Meter HF-ET-805 used for?

A: It is a handheld industrial vibration tester for rotating machinery. It measures acceleration, velocity and displacement to assess equipment running condition and detect early mechanical faults.

Q2: What type of probe does HF-ET-805 adopt?

A: It is equipped with a piezoelectric shear‑type accelerometer probe for stable and reliable vibration acquisition.

Q3: What measurement values can this meter output?

A: It measures acceleration, vibration velocity and displacement. Measurement ranges: ‑ Acceleration: 0.1‑199.9 m/s² peak ‑ Velocity: 0.1‑199.9 mm/s RMS ‑ Displacement: 0.001‑1.999 mm p‑p

Q4: What is the measurement accuracy and frequency response?

A: Accuracy: ±5% ±2 digits. Frequency range: 10Hz‑1kHz for velocity & displacement; 10Hz‑15kHz for acceleration.

Q5: What is the power‑supply working time?

A: Powered by one 9V battery, about 25‑hours continuous working time. It will auto‑power‑off after 1‑minute to save battery.

Q6: Does it support data hold function?

A: Yes. Press the MEAS key for measurement; release the key to hold the reading on screen.

Q7: What is the AC signal output for?

A: Full‑scale 2V AC output. It can connect to external recorder for further signal analysis, load impedance shall be above 10kΩ. VP‑37 earphone is also supported.

Q8: What are included in standard package?

A: Main unit, soft carrying case, 9V battery, short probe, strap and operation manual. Long probe and earphone are optional spare parts.

Q9: Readings keep zero when measuring

A: Check battery power; confirm probe is tightly attached to measured surface; verify MEAS key is pressed correctly.

Q10: Unstable / floating vibration readings

A: Ensure firm probe contact. Avoid probe shaking. Keep away from strong electromagnetic interference sources.
