Diagnostic Screen
The diagnostic screen can be displayed by holding down the file button for
approximately 2 seconds. This screen displays information about the operation of
the 699A07. The information found in this menu is displayed in real time:
Reference ICP Bias Voltage
Test Sensor Bias Voltage
Test Sensor Type: Voltage, ICP® or Modulated Current
Signal Type: Internal or External
Reference THD
Sensor THD
Exit the diagnostic screen by pressing the file button.
TEST SENSOR IN Input BNC
The 699A07 provides the capability to measure the test sensor’s voltage signal,
replacing the need for an external DMM or data acquisition. The input electronics
can be configured for Voltage, ICP® or Modulated Current mode as described in
Step 4 of Basic Operation earlier in this manual.
The TEST SENSOR IN input BNC is capable of measuring a voltage input of up to
10V AC pk-pk. As an ICP® sensor signal conditioner, it measures up to 10V pk-pk
AC signal while supplying 5mA ICP® constant current at 25V DC. While in ICP®
mode, the input circuit is also monitoring the ICP® sensor Bias Voltage and will
indicate a Bias Fault when the DC voltage is below 2V DC or above 15V DC. The
open circuit voltage of the ICP® supply will be 25V DC. This open circuit and the
ICP® Bias Voltage may be checked using the diagnostic menu.
