Chapter 2 — The pH/mV Amp

First make sure that the
e-corder
is turned off. Then connect the I
2
C
cable to the I
2
C connector on the back panel of the
e-corder
, and the
other end to the I
2
C Input connector on the back panel of the pH/mV
Amp. Use BNC cables to connect the signal outputs on the back panel
of the Quad pH/mV Amp to the front panel of the
e-corder
as shown in
Figure 2–4
and
Figure 2–5
.
Check that all connections are firm. Loose connections may cause
failure to recognize the eDAQ Amp by the software, erratic behavior,
or loss of signal.
Multiple eDAQ Amps can be connected to an
e-corder
. The number
that can be connected depends on the number of input channels on the
e-corder
. The initial eDAQ Amp should be connected as shown in
Figure 2–4
. The remainder are linked via I
2
C cables, connecting the
I
2
C output of one eDAQ Amp to the I
2
C input of the next, as in
Figure
2–5
. The signal outputs of each eDAQ Amp are connected to an input
channel of the
e-corder
.
The pH/mV Amp Self Test
After you have installed the software, connected the
e-corder
to a
computer as described in your
e-corder Manual
, and connected the
pH/mV Amp as described above, a quick check can be performed on
the pH/mV Amp:
• Turn on the e-corder and check that it performs its normal
diagnostic tests, as described in the
e-corder Manual
• Once the e-corder is ready, open Chart or Scope.
• During initialization, you should see these indicators flash briefly
and then remain lit — the Quad pH/mV Amp is ready for use.
If the indicators do not light, check your cable connections and repeat
the procedure. If this does not solve the problem, contact your eDAQ
distributor.
