What to do if there is no analog output voltage in MKS 903?
If the MKS Measuring Instruments show no analog output voltage, first ensure the D-sub is properly connected and the power supply is turned on. If the issue persists, the PC board may be defective and require repair by MKS.
What to do if analog output voltage is less than 0.5 V and green LED OFF in MKS 903?
If the analog output voltage is less than 0.5 V and the green LED is OFF on your MKS Measuring Instruments, verify the cable connection and ensure the power supply is turned on.
What to do if analog output voltage is less than 0.5 V and green LED ON in MKS 903?
If the analog output voltage is less than 0.5 V and the green LED is ON for the MKS Measuring Instruments, the supply voltage may be too low. Increase the supply voltage to provide 14 to 30 V at the sensor.
What to do if analog output voltage is less than 0.5 V in MKS Measuring Instruments?
If the analog output voltage of your MKS Measuring Instruments is less than 0.5 V, it could be because the discharge has not started yet, so wait for discharge to start, or increase pressure to speed up starting time. Also, consider purchasing an IgniTorr™. Alternatively, the pressure might be less than 3 x10-10 Torr, which is beyond the range. Increase pressure if desired.
