Daily inspection of force gauges

For long-term use of force gauges, IMADA recommends daily inspection of force gauges.

1. Check the displayed value

For all measuring instruments, including force gauges, accurate display value is essential. The accuracy of the display values is confirmed by comparing the relationship between the display value of the standard instrument and the value of the measuring instrument, and this is called the calibration procedure. Regular calibration and accuracy adjustment is essential to maintain the measurement accuracy of the instrument.

A force gauge calibration checks whether the measuring instrument's displayed value is within the tolerance range when a constant load is applied accurately. However, accurately applying constant load is complex and requires sophisticated tasks and investment in equipment installation. Therefore, it is not easy to set up a calibration system individually, and in most cases, the manufacturers of the measuring instruments or the specialized calibration organizations perform the calibration. About IMADA’s Calibration Service>

Regular periodical full-scale calibration by the calibration specialists is essential. Additionally, there are means to perform basic calibration in-house. This helps users detect issues and irregularities immediately and positively affects risk management, such as quality control. IMADA recommends the following 2 in-house calibrations: A) Calibration with the Tabletop Calibration Unit, B) Calibration with a Calibration Stand

A) Calibration method using the Tabletop Force Gauge Calibration Unit

The method with IMADA's Tabletop Force Gauge Calibration Unit TFCU series and a force gauge with reliable accuracy is used as a standard to compare the force gauge value to be calibrated. The measuring shafts of two force gauges are pressed against or pulled to check for noticeable measurement value differences. Calculation based on the value displayed and the specification accuracy enables the understanding of the current accuracy range of the measuring instrument. Additionally, recording the daily calibration results helps to locate the noticeable change in the measurement values, which helps with early problem detection.

Less expensive and space-saving compared to calibration methods using a calibration stand and weights
Easy to operate, and no special training is required
Periodic calibration service for standard force gauges is also provided by IMADA

B) Calibration method using a Calibration Stand, Calibration Plates, and Weights

For this method, a force gauge is mounted on a calibration stand. The method involves hanging a calibration plate to the measuring shaft of the force gauge, and weights are added to check the values on the display. The calibration stand / calibration plates are made-to-order by IMADA, and it would be possible to practice with specialized in-house calibration, as shown in the video, for your information. *The standard weights are not available from IMADA.

2. Confirm Basic Operation and Appearance

The following items, other than the display values, are recommended for daily inspection.

External appearance check: No unnatural dents or damage, no signs of tilt or distortion of and around the measuring shaft, etc.
Basic operation check: screen display, response to button operations, etc.

Suppose any unusual signs or irregularities are identified, our advice is to stop using the measuring instrument immediately for safety and request repairment.

3. Storage

Please take note of the following points, especially if the product will not be used for an extended period:

Store in the provided case: This is to prevent the sensor from being overloaded due to accidental drops or unintended contact.
Keep in a location free from significant vibrations: For the same reasons as mentioned above.
Temperature: 0-40℃, Humidity: 20-80% RH in a non-condensing environment: Adhering to these storage conditions will minimize the risk of malfunction.

Risks and Measures for Long-Term Inactivity:

For digital products, there is a risk of not being able to use them due to over-discharge. To prevent this, please charge them periodically.
We recommend calibration every year. Especially if the product has been stored without use for over a year, we strongly recommend sending it for calibration before use.

*Please note that the above precautions do not guarantee that the product will not malfunction.
