The load resistance connected to T-51KAA is fixed. In the case of current output, please specify a
resistance value no more than that shown in the table above; specify a resistance value no less than that
shown in the table above in the case of voltage output.
Error may occur when the input waveform is distorted.
For example, when the third harmonic content is 15%, the error is approx. ±5% for T-51KAA, ±2% for
T-51HAA and ±0.2% for T-101SAA.
