2. Connect RIY as shown in figure 4. Apply power.
3. Press and hold either the Up
or Down ZERO push button.
Note zero value displayed.
4. Press and hold either the Up
or Down SPAN push button.
Note span (full-scale) value
displayed.
5. To enter zero calibrate mode,
press the Up and Down
ZERO push buttons simulta-
neously.
NOTE
In standard ranging, the LCD will
continually flash while in the calibrate
mode.
6. Set input device for zero-percent input to RIY.
7. To capture zero input value,
press (slowly) the Up and
Down ZERO push buttons
simultaneously, twice.
NOTE
If the input value being captured
exceeds the upper or lower programmed
table limits for a particular input (refer to
table 2), the LCD will flash -HI- or -LO-,
respectively. The input value must be
within programmed table limits to be
displayed or captured.
8. Verify that voltmeter reading is 5 Vdc (equivalent
to 20 mA). This indicates that zero input value
was captured successfully. If voltmeter reads 1
Vdc (4 mA), repeat steps 6 and 7 until 5 Vdc
reading is obtained.
9. Set input device for full-scale input to RIY.
10. To capture full-scale input
value, press (slowly) the Up
and Down SPAN push
buttons simultaneously,
twice.
11. Verify that voltmeter reading is 1 Vdc (4 mA).
This indicates that full-scale value was captured
successfully. If voltmeter reads 5 Vdc, repeat
steps 9 and 10 until 1 Vdc reading is obtained.
12. To trim zero-percent output,
while monitoring output,
press the Up or Down ZERO
push button until desired
output reading is obtained
(e.g., 1.000 Vdc).
13. Press the Up and Down
SPAN push buttons simulta-
neously.
14. To trim 100-percent output,
while monitoring output, press
the Up or Down SPAN push button until desired
output reading is obtained (e.g., 5.000 Vdc).
15. When desired values are
captured and outputs
trimmed, press both Up
arrows simultaneously to
save latest settings.
16. Check zero and full-scale settings as described in
steps 3 and 4. If settings are correct, standard
ranging is complete. If not, repeat entire proce-
dure.
17. When procedure is complete, set SW301-6 to the
‘on’ position for keyboard lockout (for units with
SW301-6 functional).
