factor a request for external calibration will be issued after selecting this gas. If a
calibration factor is entered the HLD5000 may be calibrated with the internal
calibrated leak as for all other gases from the list.
BUTTON
The HLD5000 permits the entry of different configurations as to the operation of the
button in the probe so as to allow different working and test methods to be
implemented:
UNIT
Here the unit of measurement required for the measurements can be selected. One
may select from g/a; mbar x l /s; lb/yr; oz/yr and Pa x m
3
/s.
For the Smart probe only g/a, oz/yr and lb/yr are available. When switching from a
pre-programmed gas to a user-definable gas the HLD5000 will default to g/a.
4.1.2 VOLUME
Here the loudspeaker may be switched "OFF” or "ON”. When selecting "ON” the
volume may be adjusted from 1 (quiet) to 20 (loud) with the aid of the arrows
↑
and
↓
.
With the Test button the selected volume can be checked.
The error sound is a two-tone sound.
4.1.3 CONTRAST
Through this function one may set up the contrast for the LC display. For this press
the keys "brighter” or "darker” as required until the desired level of brightness has
been attained. The range spans from 1 to 99.
"OFF" "
OFF
” means that the button in the probe is disabled (except during the
calibration process, see Chapter 4.5.2 ). The rejection leak rate (
LEVEL
)
set up under the menu item "
TRIGGER
” is used, the alternative rejection
leak rate does not apply here.
"ALT" "
ALT
” should be selected if a unit under test is to be tested at two
different points at differing sensitivities. If the button on the probe is not
pressed the rejection leak rate set up under "
LEVEL
” will apply. When
operating the button, then the alternative rejection leak rate will apply
(as set up under "
ALT LEVEL
”).
"SEARCH" With the setting "
SEARCH
” selected it is possible to quickly sniff the unit
under test at a high sensitivity defined by the HLD5000 with the button
on the probe not pressed. As soon as the HLD5000 has detected a
leak, the button may then be pressed to determine if the leak found
exceeds the rejection leak rate as set up under "
LEVEL
”. The alternative
rejection leak rate is not available in this mode. In the main menu and
with this setting, Search (Test) will be displayed when button on at the
handle is not pressed.
