Calibration & Setup Procedure for ITC-79-FTF
1. Factory Settings: (unless otherwise specified at time of order)
ITC-79-FTF:
ITC-79-FTF-BUF:
ITC-79-FTF-DIV:
2. Input Type:
Determine the type of input that is to be applied to the ITC-79-FTF (choices are
Voltage, Dry Contact, AC or DC Coupled ).
on which input type you are using:
Voltage Input:
Several input ranges for various voltage levels can be set up by jumpers H2-5
through H2-8.
Dry Contact Input:
Insert
select a 0-10 V input
the OFF threshold to +5 V (using TP2).
AC or DC Coupling:
The ITC-79-FTF is set up for DC Coupling by default.
AC Coupling, remove jumper J1 and replace it with a 1 uF capacitor.
3. Input Response Time:
There are four response times to choose from for the input conditioning circuitry.
These response times help eliminate noise on the input signal.
time that is adequate for your particular frequency input.
highest frequency that is to be accepted by the input has a period greater than the
chosen response time.
