2. HOW TO SET CCA-40A How to set the CCA card is conducted entirely from the EDX-2000A screen. Settings and measurement of the CCA card are conducted in due order as described in the following table. EDX-2000A Initial Screen ↓... - Page 20 EDX-2000A, CCA-40A appears as the “Card Type” in the “Slot No.” column. (The screen at the right shows that ‘1’ CCA-40A is installed in the slot No. 1) Here, select the item 2) Condition from the main menu and press the ENTER key.
- Page 21 Channel Cond Select item 1) <Channel Cond> from <Condition> main menu to display the screen at the right. Here, point the cursor to the desired item and press the ENTER key. MEAS Channel Select 1) <MEAS Channel> from the <Channel Cond> menu to display the screen at the right with a “MEAS Channel”...
- Page 22 Mode Select 2) <Mode> from the <Channel Cond> menu to display the screen at the right with a “Mode” setting window. For normal use, select 0) Voltage. NOTE Since item 1) “Reserve” is a reserved mode, do not select the “Reserve” mode. Or, no measurement is made for signal output from sensor that is connected to a CH with “Reserve”...
- Page 23 Examples of setting range is described in the following: When the accelerometer sensitivity = 10.20 [mV/m/S ] (100 mV/G, 1 G=9.80665 m/S ) and estimated maximum acceleration = 147.1 [m/S ] (15 G), the estimated maximum input voltage shall be obtained by the following expression.
- Page 24 Sampling frequency range usable for the antialising filter is 100 Hz or more. Although the card type is CCA-40A-F, if “AUTO” is not displayed on the “Low Pass Filter” setting window, check whether or not the sampling frequency is set to less than 100 Hz.
- Page 25 CAL ON/OFF Select 5) <CAL ON/OFF> from the <Channel Cond> menu to display the screen at the right with “CAL ON/OFF” setting window. Here, set the cursor to “ON” or “OFF” and press the ENTER key. Only CHs that are set to “ON” are allowed for entering CAL value when conducting the measurement.

- Page 27 NOTE If channel of 20 mV range and that of 5000 mV range are mixedly used in the same card, crosstalk may occur resulting to display a waveform that is different from the input waveform of the channel of 20 mV range. [Reference] <The most affected example>...
- Page 28 NOTE When the CCA card power is ON, when the input connector is disconnected, when the sensor is removed, measuring range is changed, or when excess signal is entered, the output voltage may largely varies. But it is not faulty. Although the time required until the output voltage becomes stable varies according to sensors in use or CCA card measuring range, the output voltage becomes stable in approximately 20 to 40 seconds.
