Line Fault Recording with the METRA HIT 29S
21.1
Line Fault Recording without Memory Mode
The measuring instrument provides for the continuous log-
ging of line voltages and line faults. The following line faults
can be recorded: violation of predetermined upper and
lower limit values (LO, HI), mains failure (drop out) and pos-
itive and negative pulses (+/–pulses). Each of these events
is stored to intermediate memory and can be subsequently
queried. The type of event, the time of occurrence and
duration (except for pulses) are displayed.
Events remain in intermediate memory until the line fault
recording mode is exited. Approximately 250 events can
be stored to volatile memory without activating the mem-
ory mode.
These events can be stored at the instrument as a com-
pressed data file in the memory mode (see chapter 21.3),
and can be uploaded to a PC later.
➭
The limit values must be entered in the setup menu
before measurement is started, if these have not already
been set (see chapter 23).
➭
Set the rotary switch to “V
“.
➭
Repeatedly press the
ESC|FUNC
key until StorEd is dis-
played (immediately follows EVENTS display).
➭
Basic Display: As soon as the multimeter records an
event, the type of fault is first read out to the sub-display,
which is followed by the display: “StorEd”. At the same
time, the consecutive number assigned to the stored
event appears in the right hand sub-display. This number
represents the total number of stored events.
➭
Display 1: You can scroll from one stored event to the
next with the
V
(previous events) and
U
(recent events)
keys (right hand sub-display). The type of line fault
appears at the main display, and time of occurrence
appears at the left hand sub-display (with clock symbol).
Display 1 is exited by activating the
ESC|FUNC
key, upon
which the basic display reappears.
Note!
☞
The multimeter continues recording new events,
even when you scroll through previously stored
events. If two events occur simultaneously, only one
is displayed, although both are correctly stored.
