These include a tool for Interval Analysis, which enables users to report quickly on device performance by scientifically analysing historical data and drift to allow informed and qualified calibration interval recommendations (which may be longer than manufacturers' recommendations).
Determine your calibration interval by checking TMDE's TB 43-180, Calibration and Repair Requirements for the Maintenance of Army Materiel.
Normally, conductivity sensors are not subject to much wear and the calibration interval according to the DIN EN 27888 standard is half a year.
The sensor's stability results in an extended calibration interval of 12 months, reducing calibration time and maintenance costs.
For example, if testing is done at a time of year that provides a significantly varying temperature range over the antenna calibration interval, the heating or cooling of the cable can introduce errors.
Students may further like to integrate measurements of the UV irradiance measured over the calibration interval (Table 1) using different techniques to obtain more accurate estimates of the exposure for each dosimeter.
Lower maintenance costs with a 2-year calibration interval.
If and when "before" calibration data reveals that the chart recorder or data logger has stayed acceptably close to the stated accuracy of the instrument then you can continue to stretch the original calibration interval.
If the results still exceeded the calibration interval after this reduction of sample volume, approximate concentrations were estimated by extrapolation.
Check sensor calibration several times during the regular calibration interval.
This DAQ series also offers a desirable design for calibration at every input range, reportedly improving measurement accuracy by up to five times in addition to extending the recommended calibration interval on most M Series devices to two years.
In addition to its high performance levels, the 4288A reduces maintenance costs by extending the calibration interval to one year, and it consumes only 35 W of power at 100 VAC.
