Operation; Pen Scaling - Instron 4400 Series Operator's Manual

Strip Chart Recorder
Plug the recorder input cable (A570-26), provided with
the unit, into the ANALOG OUT connector on the rear
of the console. Connect the other end of the cable into
the 9-pin D-shell connector on the right-rear corner un-
derneath the recorder.

Operation

The Series 4400 system does not provide any control
functions for the recorder; it merely supplies an analog
data signal which is scaled and plotted by the recorder.
Thus, operation of the recorder is covered in an Operat-
ing Instructions Manual supplied with the recorder,
where you will find the necessary control settings, setup,
and operating information. The following sections give
the procedures for using the recorder with the Series
4400 Testing System. The procedures given are for a
one pen (single channel) recorder, and thus all values are
given in terms of load. Scaling and calibration proce-
dures for the second channel (Strain) are identical to the
load channel procedures.

Pen Scaling

Pen scaling can be set at the recorder so that zero and
full scale fall exactly at the edges of the chart. If these
two points are accurate, then the scale divisions printed
on the chart can be used to accurately determine the
value of all other points on the test curve.
To scale the recorder pen for a load signal:
(a) Press the 0 (ZERO) button on channel 1 of the re-
6-8
corder. This removes all input signals and shorts the
input for a no-signal condition.
