Operating the TTI-7-R
5.4.5 Setting up a PRT measurement: checking/editing probe
memory co-eff. values
This allows you to assign coefficient values to probe memories or
check the values already assigned.
1.
Press 3/SENS and if PRT and TC inputs used, the screen
requests
[
PRT
]
or
[
TC
]
. When only a PRT channel is
available (NO channel expansion modules fitted) the screen
shows:
Standard?
IEC US/ EN-
Rev 751 JIS 751 Usr Quit OK
2. Select the [Rev] option. If you have already selected one of
the three standard linearizations, the four pre-programmed
standard coefficients are displayed at the top of the screen.
These cannot be altered.
3. If you want to enter a new set of coefficients, press
User in ‘Standard’ screen above. The screen requests
a probe coefficient set 1 to 20. Enter an empty
memory box number, e.g. 11. The screen displays:
User 11 empty
Enter Quit
4.
Select enter. The screen shows:
IPRT SPRTCVD ITS90
5. Select required probe coefficient type, e.g. SPRT, ITS90
and the screen shows:

.
6. Select and enter each coefficient in turn. (If no coefficient
exists, do not enter any value). To enter the coefficient,
e.g. –3.98e-2. first put in a – sign, then the number 3.98
from the front panel keys. For the exponential form, press
the exponential key on the front panel (on the lower right
