10. t on the performance of this instrument due to the temperature coefficient of the resistance under test and thermal EMF across dissimilar conductors Most conductors have a large temperature coefficient of resistance For example 0 4 C for copper So a copper conductor that has a resistance of 10mQ at 20 C will increase to 10 4mQ at 30 C This change should be taken into account when making measurements When passing a current through a resistance it will generate heat so the duration of the test can also change the resistance value For items such as current shunts which have joints of dissimilar conductors the thermal EMF can affect the accuracy of the measurement This condition can be detected if the reading alters when then leads are reversed To compensate for this do the test in both directions and the average of the two readings should be taken as the true measurement 2 Wire Method When using a high resistance range such as 20002 it is not necessary to use the 4 wire method as the 2 wire method should be accurate enough Q A PI G LD TA PaA JAX DC20V CE MICROPROCESSOR CONTROLLED AUTO HOLD CE 4 MAINTENANCE Metrohm products are manufactured by Martindale Electric 4 1 Calibration To maintain the integrity of measurements made using your instrument Martindale Electric recommends that it is returned at least once a year to an approved Calibration Laboratory for rec
