Status Reports
7.4 Extended Event Register
Reading the extended event register tells you whether changes in the condition register
(reflecting internal conditions) have occurred. A transition filter can be applied which
allows you to decide which events are reported to the extended event register.

The meaning of each bit of the condition register is as follows:
Bit 0
UPD (Updating)
Set to 1 when the measured data is being updated. The falling edge of UPD (1 -> 0) signifies the
end of the updating.
Bit 1
ITG (Integrate Busy)
Set to 1 while integration is in progress.
Bit 2
ITM (Integrate Timer Busy)
Set to 1 while the integration timer is running.
Bit 3
SRB (Store/Recall Busy)
Set to 1 while storing or recalling data.
Bit 4
FOV (Frequency Over)
Set to 1 when the frequency is in error.
Bit 5
PRN (Printing)
Set to 1 while the built-in printer is in operation or while data is being output to a network printer.
Bit 6
ACS (Accessing)
Set to 1 when the PC card interface, USB storage medium, or network drive is being accessed.
Bit 7
PLLE (PLL Source Input Error)
Set to 1 when there is no input to the PLL source and synchronization cannot be achieved during
harmonic measurement.
Bit 8
OVR1(Element1 Measured Data Over)
Set to 1 when the voltage or current of element 1 is overrange.
Bit 9
OVR2(Element2 Measured Data Over)
Set to 1 when the voltage or current of element 2 is overrange.
Bit 10 OVR3 (Element3 Measured Data Over)
Set to 1 when the voltage or current of element 3 is overrange.
Bit 11 OVR4 (Element4 Measured Data Over)
Set to 1 when the voltage or current of element 4 is overrange.
Bit 14 OVRM (Motor Measured Data Over)
Set to 1 when the speed or torque of the motor input is overrange.
Bit 15 POV (ElementX Input Peak Over)
Set to 1 when peak over (input exceeding the peak) is detected in any of the elements.
