Note: 1. The accuracy is for an input frequency range of 40 Hz to 1 kHz (except for AD current input A and B ranges) and an ambient temperature
of 23 ±5 ° C. The error, however, increases below 10% of the maximum input value.
DC voltage input (all ranges): 10% or less of max. input = ±0.15% FS
DC current input (all ranges): 10% or less of max. input = ±0.1% FS
AC voltage input (A: 0.0 to 400.0 V): 10% or less of max. input = ±0.15% FS
AC voltage input (B: 0.00 to 199.99 V): 10% or less of max. input = ±0.2% FS
AC voltage input (C: 0.000 to 19.999 V; D: 0.0000 to 1.9999 V): 10% or less of max. input = ±1.0% FS
AC current input (A: 0.000 to 10.000 A): 10% or less of max. input = ±0.25% FS
AC current input (B: 0.0000 to 1.9999 A): 10% or less of max. input = ±0.5% FS
AC current input, (C: 0.00 to 199.99 mA; D: 0.000 to 19.999 A): 10% or less of max. input = ±0.15% FS
When DC voltage input models are used with a ±1.9999 V range, make sure that the connections between input terminals are not open.
If the input terminals are open, the display will show large variations. Connect resistance of approximately 1 M Ω between the input ter-
minals if they are open.
2. The letters "rdg" mean "reading" and refer to the input error.
3. The value (0.5 VA CT) is the VA consumption of the internal CT (current transformer).

4. The K3HB-XVA@@ complies with UL standards when the applied input voltage is within the range 0 to 150 VAC.
If the input voltage is higher than 150 VAC, install an external transformer or take other measures to drop the voltage to 150 VAC or lower.
