Scaling Without Known Loads
(Continued)

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.

Scaling Without Known Loads

For 0–100 mV sensors, the values for the minimum and
maximum input loads are always as follows:

• Minimum load (IN!1)— 0

• 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:

2. Press /TARE. The unit displays:

3. Press /TARE again. The unit

displays the last setting for IN!1.
(The first digit flashes.)

4. Change IN!1 as necessary:

•

Press



/NT/GRS to set or change the digit's current value.

Continue to press



/NT/GRS 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 /NT/GRS 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:

Scaling With Known Loads

6. Press MENU to store IN!1. The unit

displays:

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



/NT/GRS 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 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 With Known Loads

To identify the minimum known load (IN!1 and RD!1

):

1. If it's not already shown, press MENU

until the unit displays:

2. Apply the minimum known load (0%).

3. Press /TARE. The unit displays:

4. Press /TARE again. The unit

displays the last setting for

IN!1

.

5. Press /TARE again. The unit

displays the actual reading being
received from the sending device.

5678

To Scale the Meter

You can scale the meter in one of two ways:

1. With a known load — This method uses input (load)
information sent from another device such as a scale or a
simulator for voltage or current.

2. Without a known load — This involves calculating the load
based on transducer specifications and manually entering
it to the meter.

For both methods, you must first identify the minimum input
load IN!1 and the corresponding display reading you want
RD!1. Then you identify the maximum input load IN!2 and
its corresponding display reading RD!2.

The decimal point is for display purposes only — you set it
where you want it to display for your application. When
entering IN!1 and IN!2 values, ignore any decimal point on
the display. However, you must enter RD!1 and RD!2 values
with the decimal point in the desired position.
