Quick Ranging the TIY
To calibrate the TIY using Quick Ranging:
1. Set Range and Gain/Offset Jumpers for the
input type (See Table 4).
2. Apply DC power to the TIY as shown in
Figure 3.
3. Press and hold either ZERO push button.
Note the zero value displayed.
4. To change the zero setting, press both
ZERO push buttons simultaneously.
Note:
If the display begins to flash after pressing
both push buttons simultaneously, the TIY
is configured for Standard Ranging. Check
J305 (See Figure 1 and Table 3).
5. Set zero shown on LCD to desired setting
using the Up or Down ZERO push button to
increment or decrement the displayed value.
Note:
When the value entered exceeds the upper
or lower programmed table limits for a
particular input , the LCD will display -HI- or
-LO-, respectively. The value entered must
be within programmed table limits to be
displayed (See Table 1).
