Panel display of the PCR-M
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.
When the PCR-M is in a condition in which valid measurement data cannot be queried.
When the measurement is not complete.
When the *RST or *RCL command is sent.
On firmware version 1.19 or earlier, the voltmeter and ammeter on the front panel display are refreshed each time a new measurement is completed. If sequence operation auto continue mode is turned ON, automatic refreshing of the measured data is enabled so that the PCR-M operates as a monitor.
When continuous operation is enabled, measurement data and the front panel displays are automatically refreshed by the internal trigger loop. In this state, MEASure/READ/FECh query commands work equivalently. This means that sending multiple FETCh queries results in different measurement results, and simultaneity is lost.
When the continuous operation is enabled, the ABORt command is virtually ignored because the trigger subsystem automatically exits the IDLE state even if it is aborted.
The *RST/*RCL command resets the continuous operation to off.
|The panel display operation is different on a PCR-M with firmware version 1.19 or earlier and on a PCR-M with firmware version 1.20 or later. However, programs created for a PCR-M with firmware version 1.19 or earlier still run on a PCR-M with firmware version 1.20 or later ( except for control of panel display at timing of measurement ).|
