Compare with external standard thermistor, percentage measurement
● Available to make % measurement against standard value at room temperature regardless of temperature characterristice in comarison with external standard-termistor.
● Possible to reduce error of the measured value for Self-heating on the measuring object by pulse impress of low measuring power (Within 150μW).
● Available to measure the resistance value of external standard or to measure the resistance value of the measuring object.
● Available to calibrate the difference (±9.999%) on resistance value of external standard and to correctly measure the measuring object.
● Digital comparator is built-in.
● Measuring current/voltage-check are built-in as standard function.
