- No.1 to No.5
Plunger falling time No.1 to No. 5
- Average of falling time
Average of falling time (5 times)
- Temperature
Ink temperature measured by the sensor in the viscometer
- Standard
Standard ink viscosity at 100% ink concentration
- Viscosity
Ink viscosity (Average of falling time x Coefficient / Standard viscosity x100)
- Adjustment of viscosity (High-speed)
The "*" mark is indicated in the column during the adjustment of viscosity when the
position of initial level changed at the high-speed model.
- Control code & Control information
0: Normal
0: Normal (->Low)
0: Normal (High <-) - Increasing concentration control due to the low ink concentration
1: High Concentration - High ink concentration (120% < Ink viscosity)
2: Low Concentration - Low ink concentration (Ink viscosity < 80%)
3: Instability
4: Out of range
- Initial level (High-speed machine)
The position of initial level at the high-speed machine (1 to 3) (0: At the other model)

- Reducing concentration control due to the high ink concentration
- Instability in the 5-times measurement of falling time.
(The difference between the maximum and minimum values of
falling time exceeded 10 % of average value.)
