- The measured value is not shown on the panel display (shows "----").
- The measured value is not shown on the panel display (shows ".b.y.t").
- Measurement does not start or the settings are not changed even when a trigger is sent.
- Would like to know the time needed to complete the measurement.
- An error occurs when attempting to execute the "Easy Controller for PCR-M".
Is auto continue mode on? Auto continue mode is off by default on the PCR-M.
Is the trigger source set to IMM (default)?
The display of the PCR-M series with firmware version 1.20 or later operates as a monitor. It displays the present value that is being delivered to the load.
The display of the PCR-M series with firmware version 1.19 or earlier displays the value that was measured using the INIT or MEASure command. Therefore, the PCR-M display shows "---," which signifies that there is no data, in the following cases. When the front panel control switches from local to remote.
If a concatenated command or a command that takes a long time to process is received, the PCR-M series may not be able to allocate the necessary internal memory.
When you send a command that takes a long time to process, wait approximately 250 ms before sending the next command.
Is the sequence in the WTG (Waiting for Trigger) state?
To start the measurement using a trigger, set the trigger source to BUS and send the INIT command to set the sequence in the WTG state.
Sequence 3 example
If a trigger is sent in the WTG state, measurement starts.
The PCR-M requires at most 330 ms to complete a measurement after starting the measurement operation.
If an *OPC? query is sent along with the INIT command, an ASCII character "1" is set in the output queue when all of the measurement operations are completed.
Sequence 3 example
Because the measurement is complete when this response is retrieved, the measured data can be retrieved using the FETC? query.
For sequence 1, change INIT:SEQ3 to :INIT.
Has your computer installed the "VISA Library"?
One of the "VISA Libraries" is required in your computer to execute for the "Easy Controller for PCR-M".
If the error still appears even when the "VISA Library" is installed in your computer, please try to re-install the "VISA Library".。
As for the detailed installation of either library for such "NI-VISA" or "Agilent VISA", please refer to the instruction manual respectively.
