Section 3. Specification
3.1 Controller EA-5J
Measurement mode: Manual mode, Auto mode and PC mode
[]Manual mode
Ion balance mode: Display shows the plate voltage.①
- LCD display renewal rate can be set: 0.2, 1, 5 and 10 seconds.
0.2 sec.: Average value of 10 points data excluded the maximum and minimum
value for 20 ms is showed on the display.
1 sec.: Average value of 50 points data excluded the maximum and minimum
value for 20 ms is showed on the display.
5 sec.: Average value of 250 points data excluded the maximum and minimum
value for 20 ms is showed on the display.
10 sec.: Average value of 500 points data excluded the maximum and minimum
value for 20 ms is showed on the display.
- Measuring time can be set: 10, 30, 60 seconds and continuous.
After measurement, average value, peak value and valley value in the set time
areshowedonthedisplay.
Decay time mode: Display shows the plate voltage and the decay time.②
- During measurement: Display shows average value of the plate voltage.
Averaged value of 5 points data excluded the maximum and minimum value for
20 ms.
- The end of measurement: Display shows the decay time.
Fast mode: 0.1 99.9 seconds, Slow mode: 100 300 seconds.～～
- Measuring time can be set: 10, 30, 60, 120 and 300 seconds.
- The polarity can be chosen: The decay time can be measured at the positive and
thenegativepolarity.
- The stop voltage can be set from 5 to 100 volts in 5 volts increments.
[]Auto mode
Decay time measurement: Measurement under the conditions of the set time and①
stop voltage. It measures and saves the data automatically at the both polarity of
negative and positive.
Ion balance measurement: Measurement continuously within the time set. The case②
of continuous con setting, the time is 120 seconds. Average value, peak value()
maximum value and valley value minimum value are saved in the memory.() ()
Data saving: After measurement, all value are saved in the internal memory by③
pressing the SAVE button. Data can be saved up to 1000.
