a strain gage (0-3.33 mV/V full scale) signal output. Amplified units have a number where the strain
gage units have a letter (E or A). The PT4624-5M-6/18 has a 4-20 mA signal output; the PT4625-5M-
6/18 has a 0-5 VDC signal output, while PT4626-5M-6/18 has a 0-10 VDC signal output. In
Industrial applications, amplified units have a middle or end number of 4, 5, or 6. The S840-000-1C
has a 4-20 mA signal output; the PT150-7.5M has a 0-5 VDC signal output, while PT276-5M has a
0-10 VDC signal output.
The ATC770’s default setting is strain gage input. To verify that the input is set for strain gage, press
the FUNC key until
nonE
and
GROUP
show on the display. Press the ▲ key until
5
shows in the
upper display. Press the FUNC key and the upper display should show
Str
while the lower display
shows
PI.TYP
. If not, press the ▲ or ▼ key until the upper display changes to
Str
(for strain gage).
Press the FUNC key to set the value. Press the A/M key to return to the active display. Remember to
change the jumper settings to correspond to the proper input as shown in Figure 7 for board location
and Figure 8 for amplified input jumpers.
