HBMA0114-6.3 en
• Measuring frequency range
The measuring frequency range is 10 Hz.
• Zero point
- Discharge the transducer or charge with preload.
- Use digital voltmeter to measure output voltage, and use rotary switch S23
to adjust minimum indication (if necessary, use S22 to switch polarity); fine
balancing with P21 to 0.000 V.
• Measuring range
To obtain the maximum measurement resolution, the max. amplifier output-
voltage ("10 V) should be used.
