power on/off via the OK pushbutton. To power on or off, hold the OK
button down for 2 to 3 seconds.
3. If possible, use a network connection for improved response times
and faster data acquisition. Connect to an ethernet switch and the
MWM
will attempt to determine an
IP
address via
DHCP
. If that fails,
it will default to an internal
IP
which will be shown on the instru-
ment display. See chapter B for more information on configuring
communications parameters.
4. The
MWM
must be coupled to the light source via a single-mode opti-
cal fibre. Multimode fibre is
not
suitable. The instrument sensitivity
is very high and so the fibre mode diameter need not be well matched;
for example, a 480 nm fibre can be used to measure 780 nm light and
vice versa, though best accuracy and stability are achieved if the
fibre is matched to the wavelength. Fibres with
FC/PC
(preferred)
or
FC/APC
connectors can be used, and standard or polarisation-
maintaining fibre.
Note:
Your device has been configured and calibrated using a fibre
with either FC/PC or FC/APC connector, usually with FC/PC at the
wavemeter. Please refer to the test data provided with your device.
If you use a different connector type, you will need to reconfigure
and recalibrate. Please see section 4.8.
Caution:
The fibre tip is an integral part of the instrument. Unclean
