Calibration Setup

Table 1 lists the equipment you will need to calibrate
the IST.  These items are not supplied by Moore In-
dustries, but should be available in environments
qualified to perform the procedure.

Figures 2 and 3 show the calibration setup for the
single and dual IST.  Connect the unit as shown in the
illustration, and apply appropriate ac power.  Allow
approximately five minutes for setup stabilization/
warm-up.

Use the appropriate materials listed in Table 1 in the
hookup, apply appropriate power, and allow approxi-
mately 5 minutes for unit warm-up and hookup sta-
bilization.
