You may update your software through the Internet by clicking the
Check for updates
command in the spectrum field context menu. You can also find this command on the
User
Manual
button menu. You can update the User Manual in the same menu.
ZaIR 3.5
supports Windows XP, 7, 8 and 10 operating systems. The
gdiplus.dll
module
may be missing in minor Windows versions. The module is included in the installation
software. If
z35.exe
fails to find
gdiplus.dll
, copy this file from the
GDIPLUS
folder to the
program-operating folder.
Use the standard
Control Panel
and
Add and Remove Programs
windows to remove the
device driver and software.
First run
Use the rear panel switch to turn on the device, the
Power
indicator on the front panel
will light green. In case the device driver was not installed at the first step (Section 3.2) or
the device has been off for a long time (a few days), Windows will ask to refer it to the
IROS
05
device driver. Do not search for the driver on the Internet, choose automatic installation
and specify
C:\z35\ FTD2XX
as the file source path.
Run the device software. In a few seconds, the green
Scan
LED will start blinking on the
device case with a frequency of 1 time per second or less depending on the current spectral
resolution. The lighted LED means carriage forward stroke, dark LED means carriage return.
You can find a similar indicator in the bottom right corner of the software window. It is usually
a light blue circle that shifts right and left and right to indicate forward and return scans. The
triangular icons there indicate scan errors. Single errors can be caused by the device being
pushed or shaken. If errors keep occurring, or the LED on the case stops blinking, and the
software window indicator looks different from usual, it can mean device or software failure.
In this case, restart the program. If it does not help, unplug and again plug in the USB cable
or, in the worst case, turn off the device for a few minutes {see the troubleshooting section).
You can start recording spectra in 10 minutes after turning on the device and running
the software, we recommend that you start high precision measurements in an hour or later.
This is the time for the device to reach a thermal equilibrium. After changing the resolution,
you should also wait for a few minutes before you start recording.
Turn off the device for long idle periods {such as night). You have to turn the device off
before changing the computer or its parts, as well as before moving the device anywhere.
Spectrum recording
The main spectrum recording settings and commands are in the
Record
toolbar (Fig. 3).
The spectral
resolution
, or the minimum distinguishable distance between two peaks
can be set to 8, 4, 2, 1 or 0.5 cm
-1
. To do so, click the
Resolution
button and choose the value
you need in the menu. The current value is indicated on the button itself. Note that the
distance between spectral points is almost half the resolution value and is not divisible by it
but depends on the built-in laser wavelength (e.g., resolution 4 cm
-1
corresponds to 1.93 cm
- 1
between the points). The default resolution is 4 cm
-1
that is used for the qualitative analysis
of organic compounds. The better the resolution, the longer are the scans and the lesser is
the green light flashing frequency.
