SECTION 1. INTRODUCTION

1.1 UNPACKING

Remove the Packing List and verify that all equipment has been received. If there are
any questions about the shipment, use the phone numbers listed on the back cover to
contact the Customer Service Department nearest you.

Upon receipt of shipment, inspect the container and equipment for any signs of damage.
Take particular note of any evidence of rough handling in transit. Immediately report any
damage to the shipping agent.

The carrier will not honor any claims unless all shipping material is saved for
their examination. After examining and removing contents, save packing
material and carton in the event reshipment is necessary.

Verify that you receive the following items in the shipping box:

QTY DESCRIPTION

1 Programmable Digital Meter indicator/controller with all applicable

connectors attached.

1 Owner's Manual

1 Set Mounting brackets

If you ordered any of the available options (except the "BL" Blank Lens
option), they will be shipped in a separate container to avoid any damage to
your indicator/controller.

1.2 SAFETY CONSIDERATIONS

This device is marked with the international caution symbol. It is important to
read this manual before installing or commissioning this device as it contains

important information relating to Safety and EMC (Electromagnetic Compatibility).

This instrument is a panel mount device protected in accordance with EN 61010­1:2001, electrical safety requirements for electrical equipment for measurement, control
and laboratory. Installation of this instrument should be done by qualified personnel. In
order to ensure safe operation, the following instructions should be followed.

This instrument has no power-on switch. An external switch or circuit-breaker shall
be included in the building installation as a disconnecting device. It shall be marked to
indicate this function, and it shall be in close proximity to the equipment within easy
reach of the operator. The switch or circuit-breaker shall not interrupt the Protective
Conductor (Earth wire), and it shall meet the relevant requirements of IEC 947–1 and
IEC 947-3 (International Electrotechnical Commission). The switch shall not be
incorporated in the main supply cord.

Furthermore, to provide protection against excessive energy being drawn from the
main supply in case of a fault in the equipment, an overcurrent protection device shall
be installed.

• 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.

• Unit mounting should allow for adequate ventilation to ensure instrument does not
exceed operating temperature rating.

• Use electrical wires with adequate size to handle mechanical strain and power
requirements. Install without exposing bare wire outside the connector to minimize
electrical shock hazards.

EMC Considerations

• 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 wires close to the instrument if EMC problems
persist.

Failure to follow all instructions and warnings may result in injury!!

SECTION 2. ABOUT THE METER

2.1 DESCRIPTION

The Digital Programmable Strain meter is a value packed indicator/controller. Four full
digits and broad scaling capability allow for display in virtually all engineering units.
A wide variety of DC current and voltage input ranges cover typical strain applications.
Standard features include sensor excitation and front panel or remote tare. Your meter
may be a basic indicator or it may include analog output or dual relay output. Analog or
dual relay output must be ordered at time of purchase. Analog output is fully scalable
and may be configured as a proportional controller, or to follow your display. Dual 5 amp,
form C relays control critical processes. A mechanical lockout has been included to
guard against unauthorized changes.

2.2 FEATURES

The following is a list of standard features:

* 4-digit, three color Programmable, Big LED display or

4-digit, Standard LED display
* NEMA 4/Type 4 Front Bezel
* ±0.03 % accuracy
* 8 DC input ranges: 0-100 mV, ±50 mV, 0-5 V, 1-5 V,

0-10 V, ±5 V, 0-20 mA, and 4-20 mA
* 5, 10, 12, or 24 Vdc sensor excitation
* Peak detection
* Front panel and remote tare function
* Nonvolatile memory-no battery backup
* 115 or 230 Vac 50/60 Hz power supply or

10-32 Vdc or 26-56 Vdc

The following is a list of optional features:

* Dual 5 amp, form C relay outputs
* Scalable analog output
* Proportional control
* Easy setup for proportional control

METER BUTTONS

SETPTS Button

In the Run Mode, this button will sequentially recall the previous setpoint settings. As
necessary, use the /NT/GRS and /TARE buttons to alter these settings, then press
the SETPTS button to store new values.

Unless you press the SETPTS,



/TARE, or /NT/GRS button within 20 seconds, the

meter will scroll to setpoint 2 and then to the Run Mode.

If the dual relay option is not installed or if L.3=1 is displayed on the LK.CF
menu, pressing the SETPTS button will display the meter's firmware version.



/NT/GRS Button

In the Run Mode, this button will toggle between net/gross readings or peak readings
depending upon setup.

In the Configuration Mode, press this button to change the value of the flashing digit
shown on the display and/or toggle between menu choices, such as R.1=R or R.1=N on
RD.CF menu. When configuring your setpoint values, press the /NT/GRS button to
advance the flashing digit's value from 0 to 9 by 1.



/TARE Button

In the Run Mode press the /TARE button to tare your reading (zeroing).

In the Configuration Mode, press the this button to scroll to the next digit.

If you hard reset (press the MENU button followed by the RESET button) or power off/on
the meter, it shows RST, followed by STRN.

In the Run Mode, press the RESET button to reset the latched setpoints. The meter
shows SP.RS and returns to the Run Mode.

In the Configuration Mode, press the RESET button once to review the previous menu.
Press the RESET button twice to perform a hard reset and return to the Run Mode.

In the Peak Mode, press the RESET button to reset peak values. The meter shows
PK.RS and returns to the Run Mode.

In the Setpoint Mode, press the RESET button to reset the latched setpoint. The meter
shows SP.RS and enters the Run Mode.

In the Tare Mode, press the RESET button to reset. The meter shows T.RST.

When in setpoint or Configuration Mode, if the meter shows 9999 or -1999
with all flashing digits, the value has overflowed. Press the

The DIP switches are located at the S1 position (refer to Figure 3-2). Use a small
instrument, such as a paper clip, to change the switches from open to closed. Table 2-3
lists DIP switch settings at the S1 position required to complete the setup of your meter.

2.6 DISASSEMBLY

You may need to open up the meter for one of the following reasons:

• To check or change the 115 or 230 Vac power jumpers.

• To install or remove jumpers on the main board.

Disconnect the power supply before proceeding.

To remove and access the main board, follow these steps:

• Disconnect the main power from the meter.

• Remove the back case cover.

• Lift the back of the main board upwards and let it slide out of the case.

SECTION 3. GETTING STARTED

Caution: The meter has no power-on switch, so it will be in operation as

soon you apply power.

If you power off/on the meter, or perform a hard reset (press the RESET button twice),
the meter shows RST , followed by STRN.

3.1 RATING/PRODUCT LABEL

This label is located on top of the meter housing (refer to Figure 3-4).

3.2 MAIN BOARD POWER JUMPERS (refer to Figure 3-1)

Important: If you want to change the Factory preset jumpers, do the
following steps; otherwise go to Section 3.3.

Warning: Disconnect the power from the unit before proceeding. This

device must only be reconfigured by a specially trained electrician with
corresponding qualifications. Failure to follow all instructions and warnings
may result in injury!

1. Remove the main board from the case. Refer to Section 2.6.

2. Locate the solder jumpers W1, W2, and W3 (located near the edge of the main
board alongside the transformer).

3. If your power requirement is 115 Vac, solder jumpers W1 and W3 should be

wired, but jumper W2 should not. If your power requirement is 230 Vac,
solder jumper W2 should be wired, but jumpers W1 and W3 should not.

Note: W4 jumper is not used.

Figure 3-1 shows the location of solder jumpers W1 through W3.
