Operation
Be careful with the following cautions during use.
Use the input within the rated range. Be careful since negligence of this caution may cause troubles of the unit.
There is a function to hold the maximum value and the minimum value with a measurement factor in this product.
The blackout this value will not be cleared by a power supply reset. However, the minimum value may be updated in
case input is not applied to a power up. Therefore the maximum value and the minimum value need to be reset of DI
after a startup, or switch operation.
For this reason, in order to recover previous minimum value, please apply input within 1 second after switching on
a power supply.
