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.

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

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.

Using This Quick Start Manual

Use this Quick Start Manual to set up your Process Meter and begin
operation. Information is provided on how to:

• Connect ac power • Set basic options for operation
Connect the sensor • Scale the meter.

Features with are for the “B” version which has three-color
programmable “Big” LED display - All segment characters shown are for
the “B” version.

IMPORTANT: For complete information on all setup options, please
refer to the Operator’s Manual.

This Quick Start Manual includes specific configuration
parameters for transducers with an output range of 4–20 mA
and 24 V excitation. Other sensor types may require different
parameters or additional ones. When this is the case, we refer
you to the Operator's Manual for detailed instructions.

Safety Consideration

This device is marked with the international Caution symbol.

The instrument is a panel mount device protected in accordance with EN
61010-1:2001, electrical safety requirements for electrical equipment for
measurement, control and laboratory. Remember that the unit has no
power-on switch. Building installation should include a switch or circuit­breaker that must be compliant to IEC 947-1 and 947-3.

SAFETY:

• Do not exceed voltage rating on the label located on the top of the instrument
housing.

• Always disconnect power before changing signal and power connections.

• Do not use this instrument on a work bench without its case for safety
reasons.

• Do not operate this instrument in flammable or explosive atmospheres.

• Do not expose this instrument to rain or moisture.

EMC:

• Whenever EMC is an issue, always use shielded cables.

• Never run signal and power wires in the same conduit.

• Use signal wire connections with twisted-pair cables.

• Install Ferrite Bead(s) on signal wire close to the instrument if EMC problems
persist.

Mount the Unit

1. Cut a panel opening using the dimen­sions shown to the right.

2. Position the unit in the opening, making
sure the front bezel is flush with the
panel.

3. Install retaining clips on both sides of
the meter and tighten against the panel.

Wiring

Warning: Do not connect AC power to your device until you
have completed all input and output connections. This device
must only be installed by a specially trained electrician with
corresponding qualifications. Failure to follow all instructions
and warnings may result in injury!

1. Remove the panel at the back of the unit.

2. Locate the TB1 connector.

3. Insert the correct wire in each terminal as shown in the following figure
and tighten the lockdown screws.

4. Tug gently on the wires to verify the connections.

External Fuse Required:

Time-delay, UL 248-14 listed Time-lag, IEC 127-3 recognized

175 mA (115 Vac line) 125 mA (115 Vac line)
80 mA (230 Vac line) 63 mA (230 Vac line)

AC Powered Unit Connections

START HERE

Wiring (continued)

When using DC power, do not use internal excitation or Isolated
Analog Output for high color brightness. For low or medium
brightness, internal excitation is limited to 24 V @ 25 mA; 5 V, 10
V, 12 V @ 35 mA.

In order to maintain the same degree of protection as the AC units,
always use a Safety Agency Approval DC source with the same
Overvoltage Category and Pollution Degree.

DC Powered Unit Connections

Connect the Sensor

1. Locate the TB2 connector on the rear of the unit.

2. Attach the sensor wires and tighten the lockdown screws.
The diagram below shows the wiring for 4–20 mA sensors with internal
excitation.

Refer to the Operator’s Manual for setup requirements for other
sensor types.

Current Input Connections (4–20 mA)

To configure the meter, you use the buttons on the front panel.

To: Take This Action:

Display the Press the MENU button. The first function
Configuration Menu on the menu, INPT, displays.

Select a submenu 1. Press MENU until the function you
function want is shown.

2. Press /TARE.

The information you can change flashes.

for that submenu you want.

function 2. Press MENU to store it.

STRD quickly flashes, indicating that
the selection has been stored in memory.
Then the next menu function displays.

Go back to previous Press RESET once.

unit displays:

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.

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:
