REQUEST
AUTO STANDBY
The HLD5000 offers the possibility of automatically reverting to the standby mode
during pauses or periods during which it is not used. A time span ranging between 1
and 15 minutes may be entered. If the HLD5000 is not used for a period of time
longer than the one set up here, the leak detector will thereafter revert automatically
to the standby mode.
When lifting the probe, the HLD5000 will automatically revert to normal operation and
will be ready to make measurements within 2 seconds.
RS232
Through this menu, the settings for the RS232 interface of the HLD5000 can be
entered.
External Calibrated Leak
Here the setting for the leak rate of the external leak can be entered.
The setting is performed as described on Chapter 4.4 and has to be confirmed with
“OK“. If for example the external leak rate is entered in g/a and changed into another
unit of measurement, the HLD5000 converts the leak rate g/a into the new unit of
measurement.
Request for
calibration Request for calibration. The HLD5000 can be set up to remind the
operator at regular intervals to run a calibration. Through this function
the automatic request to calibrate can be switched on or off whereby
the time interval can be selected in increments of 30 minutes. The
setting is entered through the keys
↑
and
↓
, and a period ranging
between 30 minutes and 24 hours may be selected. After the entered
time span has elapsed, the HLD5000 will sound an alarm and indicate
on the display a request to recalibrate.
Request for
filter
replacement The HLD5000 can be set up to remind the operator at regular intervals
to replace the filter holder at the sniffer tip. By selecting
ON
or
OFF
the
function can be enabled or disabled. When enabled the message
„Please replace filter holder!“ will be displayed every 40 hours of
operation. In this case please replace the filter holder (see Chapter
6.2.1 ) and acknowledge the message. The next request for filter
replacement will pop up after further 40 hours of operation. As factory
default the function is enabled.
Protocol Selection of the interface protocol: "OFF”, "Normal” or "Simple”.
If the RS232 interface is not used, the "OFF” setting is recommended
to exclude the possibility of any interference.
For further details on the interface protocol refer to "Interface
Description HLD5000 (kins40e1)”.
Baud rate Entry of the baud rate for the RS232 interface. Available settings are
300, 600 1200, 2400, 4800 or 9600 baud. The default setting is 9600
baud.
