To darken or lighten the LCD on the IQ
Express Dock, move the slider as
appropriate.
Battery
The battery level shown on the dock tab is
for the internal battery in the IQ Express
Dock. This battery serves to keep the real
time clock accurate while the dock is
unplugged and should not be a concern to
the user unless the battery level drops
below 2.50 Volts.
Pump Diagnostics
Pump diagnostics are controlled through the
Pump Control section on the Dock Settings
page.
Click “Pump Gas” to draw span calibration
gas through the right gas port at the back of
the dock. Click “Pump Air” to draw the fresh
air sample through the left gas input port.
Either pump will run until “Pump Off” is
selected.
Audible Alarm Sensitivity Controls
The audible alarm sensitivity controls allow
the user to customize the audible alarm test
criteria.
The Background Noise Level adjustment
offers four levels of background noise
levels. For the best
results, select the one
that most closely
approximates the
background noise
level expected during
testing.
The Minimum Sound Level setting
determines the minimum amount of sound
required to pass the alarm test. The setting
is controlled by a slider. The higher the
setting, the louder the alarm will need to be
to pass the test. The sound level is given in
decibels when the cursor is placed over the
slider.
Calibration Interval
The Dock’s calibration interval settings are
controlled from the Dock Tab and are
located below the battery level and above
the LCD Display box. The dock’s calibration
interval is the maximum number of days that
the dock will allow to pass between
calibrations for any instrument that is placed
in the dock. If an instrument is placed in the
dock and the interval has been exceeded,
the dock will automatically initiate a full span
calibration of the instrument regardless of
the results of the bump test or the
instrument’s own calibration status.
To use the setting, click on Enable Cal
Interval and set the interval to the number of
days between calibrations.
Note that this
setting overrides the instrument’s own
calibration due reminder and may cause
the instrument to undergo a full
calibration even when the instrument
itself is not due for calibration.
Gas Configuration
The calibration gas configuration settings
are located at the right side of the dock tab.
The Gas Type and Gas Value should be set
to exactly match the type and amount of
each component of the gas cylinder that is
connected to the inlet port on the dock.
