External standard type 2ch digital thermistor

checker (high current measurement type)

Compare two-measured thermistor with

external standard thermistor at one time,

percentage measurement


●Compares with external standard thermistor or polymer 

   PTC element, can be percentage measured for standard

   value regardless of temperatures characteristic at

   room temperature

●Process high speed the percentage measurement for 

   high resistance thermistor depends on Rs/Rx at the same

   time measurement

●Can be measured resistance value of external standard 

   and measured object

●The function can be corrected an error of external

   standard resistance value [±9.999%]

●Installed digital comparator for right and wrong

   judgement can be set instinctively

●Measurement current, a checking circuit of an abnormal

   measuring current are equipped as standard

●Machine interface and RS-232C interface are equipped

   as a standard


The Outline

AX-1138B selects to judge the device that is sharp at temperature change such as thermistor or polymer PTC element to compare high speed by connecting the standard device outside, it can be measured for the two Rx resistance at the same time. The function set a corrected value for a true standard is equipped to use the external standard device.

As Rs and Rx always measures at the same time, it can be percentage measurement to reduce the effect of commercial power on the high resistance measurement.
