914X Field Metrology Wells CE Comments DO NOT allow the probe sheath or inserts to drop into the well. This type of action can cause a shock to the sensor and affect the calibration. The instrument and any thermometer probes used with it are sensitive instruments that can be easily damaged. Always handle these devices with care. DO NOT allow them to be dropped, struck, stressed, or overheated. DO NOT operate this instrument in an excessively wet, oily, dusty, or dirty environment. Always keep the well and inserts clean and clear of foreign material. The Field Metrology Well is a precision instrument. Although it has been designed for optimum durability and trouble free operation, it must be handled with care. Always carry the instrument in an upright position to prevent the inserts from dropping out. The convenient handle allows for hand carrying the instrument. If a mains supply power fluctuation occurs, immediately turn off the instrument. Power bumps from brown-outs could damage the instrument. Wait until the power has stabilized before reenergizing the instrument. The probe and the block may expand at different rates. Allow for probe expansion inside the well as the block heats. Otherwise, the probe may become stuck in the well. Most probes have handle temperature limits. If the probe handle limits are exceeded, the probe may be permanently damaged. Due to a unique Air Flow Design (Patent Pending), Field Metrology Wells protect the probe handle temperature and provide a safer temperature handle for the user. 1.5 CE Comments 1.5.1 EMC Directive Hart Scientific's equipment has been tested to meet the European Electromagnetic Compatibility Directive (EMC Directive, 89/336/EEC). The Declaration of Conformity for your instrument lists the specific standards to which the instrument was tested. The instrument was designed specifically as a test and measuring device. Compliance to the EMC directive is through IEC 61326-1 Electrical equipment for measurement, control and laboratory use. As noted in the IEC 61326-1, the instrument can have varying configurations. The instrument was tested in a typical configuration with shielded RS-232 cables. 1.5.2 Immunity Testing Using Clamp-On Ferrites For the -P model only, clamp-on ferrites are provided for use in improving its electromagnetic (EM) immunity in environments of excessive EM interference. During EMC testing we found that ferrites clamped around probe cables for the Reference PRT, the PRT/RTD input, and the thermocouple (TC) input reduced the risk the EM interference affects measurements.
