... Doing so may result in electric shock, fire, or malfunction. Other Precautions • Store at the specified temperature. If the H8GN has been stored at a temperature of less than −10°C, allow the H8GN to stand at room temperature for at least 3 hours before use. • Use the product within the ratings specified for vibration, shock, submerging in water, and exposure to oil. • ...

... When the H8GN is used with power start in F mode (i.e., accumula- tive operation with output on hold), there will be a timer error (approx- imately 100 ms each time the H8GN is turned ON) due to the characteristics of the internal circuitry. Use the H8GN with signal start if timer accuracy is required. ...
