Measurement mode
|
Manual mode
|
(1) Ion balance measurement mode
Plate voltage is displayed as an average value (average value excluding the maximum and minimum values measured every 20 ms)
0.2s: Displays the average of 8 point data
1s: Displays the average of 48 point data Display
5s: Display the average of 248 points data
10s: Display the average of 498 points data
Measurement time setting (10sec, 30sec, 60sec, continuous)
Display the average value / peak value / valley value within the set measurement time
② Decay time measurement mode
Plate voltage average value display (average value excluding the maximum and minimum values measured every 20 ms)
Attenuation time display (Fast mode: 0.1 sec to 99.9 sec, Slow mode: 100 sec to 300 sec)
Measurement time setting (10sec, 30sec, 60sec, 120sec, 300sec)
Measurement for each polarity (Attenuation time is measured with positive and negative polarities)
Measurement end voltage setting (5V to 100V can be set every 5V)
|
Auto mode (automatic measurement)
|
Ion balance measurement:
Memorize the average value, peak value (maximum value), and valley value (minimum value) within the measurement time (continuous 120s) set in ion balance measurement mode
Decay time measurement:
Measurement set in decay time measurement mode
Saves the decay time of positive and negative polarities by measuring with time / measurement end voltage Data save:
After the measurement is completed, the measured values are stored in the internal memory with the “SAVE” button (up to 1000). ) Terminal can be downloaded to the computer in "CSV" format

Display
|
(1) LCD display
voltage / time is displayed digitally with 3 digits
Error / remaining battery / mode display
Bar graph display
mode display during ion balance measurement (Au, Ma, Pc, ib [IonBalance], ± dE [Decay], ERROR )
② LED display
HV OUT: Lights when high voltage is supplied to the
plate GND: Lights when the plate is grounded
+ Decay, -Decay, IB: Displays the mode being measured by the LED inside the button
CHARGE : Lights while charging the built-in battery. Red (charging), green (charging completed)
