Measurement System | The Gerdien Capacitor Method |
Measurement | There are two kinds of measurement modes, automatic measurement and manual measurement, and it chooses according to a use and can measure. ■ Automatic measurement : A positive ion and negative ion are measured automatically and the display output of the measured value is carried out. ■ Manual measurement : A positive ion and an anion are measured individually and the display output of the measured value is carried out. |
Time Base Range | Measurement range : Positive and Negative ion 0 to 5,000,000 R1= 0 to 8,000 ion/cc R2= 0 to 50,000 ion/cc R3= 0 to 500,000 ion/cc R4= 0 to 5,000,000 ion/cc |
Resolution | 1 piece/cc |
Display for Indication | Character 16-figure liquid crystal of two lines The display for indication of a STN system liquid crystal, and back light with an ON/OFF control facility |
Clock Function | The built-in clock which had a function of - part and a second at the time of year, moon, and day - is used. |
Memory Function | In order to carry out a memory, there are two kinds, automatic mode and a manual mode.500 data can be saved.■ Automatic memory :A memory is carried out with arbitrary time preset values.A preset value is 1, 2, 3, 4, 5, 10, 15, 20, 30, and 60 minutes.(It synchronizes with a built-in clock 5 minutes or more)■ Manual memory :A memory is carried out to the arbitrary time under measurement by "MEMORY switch" setup. |
Analog Output | ■ Analog output 1 (OUT1) : The measurement range under measurement, (0-1V)An analog recorder, a data recorder ■ Analog output 2 (OUT2) : The output range of R1, R2, R3, and R4 is set up. (0-1V)An analog recorder, a data recorder |
Serial Communication (RS-232C) | Data is outputted to external apparatus, such as a personal computer, in real time. It can be used for an external monitor etc.A set period is 1, 5, 10, 15, 20, 30, and 60 seconds. |
Personal Computer Output | The data which carried out the memory can be outputted to a personal computer in the Excel form. |
Printer Output | Drawing of data and digital printing are performed to a thermal printer. |
