3. Press
/TARE
again. The unit displays the
last setting for
IN!1
.
(The first digit flashes.)
4. Change
IN!1
as necessary:
• Press
/MAX
to set or change the digit's current value. Continue to
press
/MAX
until the meter displays the desired value for the
flashing digit. Values can range from 0 to 9. For the first digit, you can
also enter a minus sign (–) or –1.
• Press
/TARE
to scroll to the digit(s) you want to change.
5. Press
MENU
to store
IN!1
. The unit displays:
6. Press
/TARE
. The unit displays the last
setting for
RD!1
. (The first digit flashes.)
7. Change
RD!1
as necessary:
• Press
/MAX
until the meter displays the desired value for the
flashing digit. Values can range from 0 to 9. For the first digit, you
can also enter a minus sign (–) or –1.
• Press
/TARE
to scroll to the digit(s) you want to change.
8. Press
MENU
to store the value shown for
RD!1
.
The unit displays:
To define the maximum load (
IN!2
and
RD!2
):
1. Repeat steps 3–8 above, entering the values for
IN!2
and
RD!2
.
2. Once you've completed all steps, the unit displays:
To begin operation:
Reinitialize the unit (press
RESET
twice or
press
MENU
until
RST
flashes on the
display). When a numeric reading appears,
the unit is operational.
Determining Reading Offset
The run mode reading for meters scaled without known loads may
reflect an offset. For example, say you set
RD!1
to 0 and
RD!2
to
100, but when the minimum load is applied, a negative value of –1.5
displays on the front panel.
To correct the reading offset:
1. With zero load applied, note the reading on the display.
2. Subtract that amount from the
RD!1
and
RD!2
values you
originally entered.
In the example, the offset would be –1.5. If
RD!1
is to read 0 in
Run Mode, it must be reentered as 1.5.
RD!2
must likewise be
reentered as 101.5 if the meter is to read 100 when the
maximum load is applied.
3. Repeat the steps for "Scaling Without Known Loads," but when
the values for
IN!1
and
IN!2
display, do not change them.
Instead, press
MENU
to move to the prompts for
RD!1
and
RD!2
and make the necessary changes.
4. Reinitialize the unit and resume operation.

7. Press
/TARE
. The unit displays the last setting for
RD!1
.
8. Change
RD!1
as necessary:
• Press
/TARE
to scroll to the digit(s) you want to change
(it flashes on the display).
• Press
/MAX
to change the value of the flashing digit. Values
can range from 0 to 9. For the first digit, you can also enter a
minus sign (–) or –1.
9. Press
MENU
to store the value shown for
RD!1
.
The unit displays:
To identify the maximum known load (
IN!2
and
RD!2
):
1. Apply the maximum known load (100%).
2. Repeat steps 4–9 above, for
IN!2
and
RD!2
.
Once you've completed all steps, the unit displays:
To begin operation:
Reinitialize the unit (press
RESET
twice or
press
MENU
until
RST
flashes on the display).
When a numeric reading appears, the unit is
operational.
Scaling Without Known Loads
For 4-20 mA sensors, the values for the minimum and maximum
input loads are always as follows:
• Minimum load (
IN!1
) — 2000
• Maximum load (
IN!2
) — 9999.
If your installation uses a different sensor type, you must calculate
the values for
IN!1
and
IN!2
before proceeding with the steps
below. Use the formula provided in the Operator's Manual.
To define the minimum load (
IN!1
and
RD!1
):
1. If it's not already shown, press
MENU
until
the unit displays:
