Operation and handling of the
Ux/14-100k
•
Choose and mount the correct filter for your application (cut off
frequency as high as needed and as low as possible) to transmitter.
The filters also contain hardware for signal condition. It is essential
to use them for every setup.
•
Connect the optical fiber
•
Connect the analog signal cable to transmitter. It is recommended
to choose the cable as short as possible, since the transmitter input
(1MΩ || 10pF) is not matched to your application (avoid
oscillations).
•
Connect the output of the receiver to a suitable high-impedance
voltage measurement device, such as an oscilloscope or multimeter.
The length of the connector cable should not be significantly longer
than 1m, since the upper frequency limit is lowered by the parasitic
capacitive load.
•
Set the voltage measurement device to the expected voltage and
time range, if necessary. If used, take optional included voltage
divider into account, while setting / checking your measurement
device.
•
Turn on all devices (no order to be recognized). Communication
between transmitter and receiver will be indicated by the Signal
detect LED at the receiver.
•
The
Ux/14-100k
system is ready to use about two seconds after
turning on the transmitter.
•
Check info LED if transmission stops suddenly!
If the transmission suddenly stops after a long duration of measurement,
check the
Info
LED of the transmitter (see Figure a.1). If the battery power
falls below 5,2V, the
Info LED
is switched on. The system should be
reloaded soon. Below 4,5V, the system is turned off automatically.
The measurements can be extended by using the optional battery pack
(BP-60) with connector cable or a power supply certified by mk-
messtechnik. The external supply can be connected to the system any time
(parallel). The connection to the internal battery is decoupled with a diode.
Check info LED if
transmission stops
suddenly!
Always use external
filter! It contains
signal conditioning
hardware too and is
necessary for correct
measurements!
