Extended Event Register
The extended event register receives information about changes in the condition register, which
indicates the instrument’s internal condition. The information is the result of edge detection
performed by the transition filter.

The condition register bits are described below.
Bit 0
UPD
(Updating)
Set to 1 when the measured data is being updated.
UPD changing from 1 to 0 indicates that updating has been
completed.
Bit 1
ITG
(Integrate Busy)
Set to 1 during integration.
Bit 2
ITM
(Integrate Timer Busy)
Set to 1 when the integration timer is operating.
Bit 3
OVRS
(Σ results overflow)
Set to 1 when the computed result of Σ overflows.
Bit 4
FOV
(Frequency Over)
Set to 1 when the frequency is outside the measurement range.
Bit 5
STR
(Store busy)
Set to 1 during storage.
Bit 6
OVR1
(Element1 mesured data over)
Set to 1 when the voltage or current of element 1 exceeds its
range.
Bit 7
POV1
(Element1 voltage peak over)
Set to 1 when a peak over-range is detected in the element 1
voltage.
Bit 8
POA1
(Element1 current peak over)
Set to 1 when a peak over-range is detected in the element 1
current.
Bit 9
OVR2
(Element2 mesured data over)
Set to 1 when the voltage or current of element 2 exceeds its
range.
Bit 10
POV2
(Element2 voltage peak over)
Set to 1 when a peak over-range is detected in the element 2
voltage.
Bit 11
POA2
(Element2 current peak over)
Set to 1 when a peak over-range is detected in the element 2
current.
Bit 12
OVR3
(Element3 mesured data over)
Set to 1 when the voltage or current of element 3 exceeds its
range.
Bit 13
POV3
(Element3 voltage peak over)
Set to 1 when a peak over-range is detected in the element 3
voltage.
Bit 14
POA3
(Element3 current peak over)
Set to 1 when a peak over-range is detected in the element 3
current.
The transition filter parameters detect changes in the specified condition register bits (numeric
suffixes 1 to 16) and overwrite the extended event register in the following ways.
RISE
The specified extended event register bit is set to 0 when the corresponding condition register
bit changes from 1 to 1.
FALL
The specified extended event register bit is set to 1 when the corresponding condition register
bit changes from 0 to 1.
BOTH
The specified extended event register bit is set to 1 when the corresponding condition register
bit changes from 0 to 1 or from 1 to 0.
NEVer
Always zero.
