一组多结热转换器 (MJTC) 的相对交流-直流差异已在 30 Hz–10 kHz 频率范围内确定。这些 MJTC 具有不同的范围，并且是从多个来源获得的。当不同范围的转换器进行相互比较时，在低频下观察到差异。对于电压测量，使用与 MJTC 加热器电阻串联的匹配电阻大大减少了这些误差，也有助于减少其他误差。据信，该组的平均交流-直流差异在 160 Hz 时小于 0.3 ppm，在高达 10 kHz 时小于 0.5 ppm。
The relative ac-dc differences of a group of multijunction thermal converters (MJTC's) have been determined over the frequency range 30 Hz–10 kHz. These MJTC's are of different ranges and were obtained from several sources. Differences were observed at low frequencies when converters of various ranges were intercompared. For voltage measurements, the use of matched resistors in series with the MJTC heater resistors greatly reduced these errors and contributed to the reduction of other errors as well. It is believed that the average ac-dc difference of this group is less than 0.3 ppm at 160 Hz and 0.5 ppm up to 10 kHz.
