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 of 50 to 60 Hz) and an ambient
temperature of 23 ±5°C. The error, however, increases below 10% of the maximum input value.

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 MΩ between the input ter-
minals if they are open.

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.

The display refresh period can be lengthened to reduce flickering

Display Color Selection
Values can be displayed in either red or green. With comparative out-
