Mark defines accuracy as a percentage of full scale of the instrument. This means that any displayed reading may be higher or lower by up to 0. For example, if the displayed value is The accuracies of the sensor and the indicator must be added together. Because of these fixed errors, lower measured values will be more inaccurate as a percentage of reading.
To calculate the error as a percentage of reading, divide the fixed error by the measured value. For a 1. For a Because of the relationship between load and accuracy, we recommend selecting an instrument capacity as close as possible to the maximum measured load. A faster sampling rate more accurately captures the peak load which occurred during the test. This is especially apparent in applications where the load builds up and falls very quickly β such as the break testing of glass or ceramics.
The graphs below illustrate the advantage of a fast sampling rate:. The graph at left shows that an instrument with slower sampling rate may not accurately detect the true peak. In the graph at right, the faster rate accurately captures the true peak.
If a faster data collection rate is required, our Series 7 force gauges and indicators can collect data at up to 14, Hz, store the data internally, and bulk-download the data to a PC when the test is complete. This value represents the maximum measurable load. All available capacities are listed for each available unit of measurement. All instruments measure from 0 to the indicated capacity.
This value represents the smallest measurable increment. Pound-force Capacity x Resolution for the M force gauge is 50 x 0. This means that the gauge measures from 0 to 50 lbF, with increment size of 0. In a rush? Otherwise, please fill out the information below, and we will respond as quickly as possible.
