MODEL 1054B pH/ORP SECTION 4.0
CONFIGURATION
4.4 TEMPERATURE. Display Mnemonic t-C. Select
this item for temperature reading and compensation
choices.
A. Temperature Display. Display Mnemonic d-t.
Select this item to toggle between °F and °C temper-
ature display. The 1054B will show all temperatures in
units selected until the selection is changed.
B. Automatic Temperature Compensation (pH
only). Display Mnemonic Atc. The Model 1054B pH
will use the temperature input from the sensor for
temperature compensation when on is selected.
When oFF is selected, the analyzer will use the value
entered by the user for temperature compensation.
This manual temperature option is useful if the tem-
perature sensor is faulty or not on line. Temperature
specific faults (tcH and tcL) will be disabled (Refer
to Table 8-1).
4.4.1 Temperature Setup (t-C).
1. Enter Set Mode by pressing ACCESS key twice.
2. SCROLL (
é
) until t-C appears on the display.
3. SELECT to move to the next menu level. d-t will
display.
4. SCROLL (
é
) to display desired item, then
SELECT.
5. If d-t is selected, display will show
o
C or
o
F.
If Atc is selected, display will show on or oFF.
6. SCROLL (
é
) then ENTER desired item into
memory.
7. If
o
C,
o
F, or on are entered, display will return to
the previous level (proceed to Step 9).
If oFF is selected, the Numeric Display will flash
indicating that a process temperature value is
required (proceed to Step 8).
8. Use SCROLL (
é
) and SHIFT (
ç
) to display the
desired value. ENTER value into memory.
9. Repeat Steps 4-8 as required for other item.
10. Press the ENTER key to return to Set Menu.
4.5 CURRENT OUTPUT. Display Mnemonic OUt. This
item is used to configure the current output signal.
A. Output Dampening. Display Mnemonic dPn.
Dampens the response of the signal output. This
option is useful to minimize the effect of a noisy read-
ing. The number entered is the sample time (in sec-
onds) for an averaged output. Zero to 255 seconds
may be entered.
B. mA Output Range. Display Mnemonic CUr.
Selection of this item will allow choice of 0 to 20 mA
or 4 to 20 mA output range.
C. Display Output. Display Mnemonic d-O. This item
is used to select logic of output display. Selecting this
item will allow the 1054B pH to display current output
as mA doc or as a percent of full scale output range
Pct.
4.5.1 Output Setup (OUt).
1. Enter Set Mode by pressing the ACCESS key
twice .
2. SCROLL (
é
) until OUt appears on the display.
3. SELECT to move to the next menu level. dPn will
display.
4. SCROLL (
é
) then SELECT desired item.
5. If dPn is selected, the Numeric Display will flash
indicating that a value is required. Proceed to
Step 6.
If CUr or d-O is selected, proceed to Step 7.
6. SCROLL (
é
) then SHIFT (
ç
) to display the
desired value. ENTER into memory.
