SECTION 1. INTRODUCTION
1.1 UNPACKING
Remove the Packing List and verify that you have received all equipment. 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. Note 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 indicator/controller with all applicable connectors
attached.
1 Owner’s Manual
1 Quick Start Manual
If you ordered any of the available options (except the “ L” blank Lens
option), they will be shipped in a separate container to avoid any
damage to your indicator/controler.

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 MC (Electromagnetic Compatibility).
This instrument is a panel mount device protected in accordance with EN 61010-
1:2001, electrical safety requirements for electrical equipment for measurement, con-
trol and laboratory. Installation of this instrument should be done by qualified person-
nel. 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 incor-
porated 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.
MC 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 FRONT OF THE METER
Figure -1 shows each part of the front of the meter.
Figure 2-1. Front Panel
METER DISPLAY:
Digital LED display: ¡.9.9.9. or 9.9.9.9. 4-digit 7–segment, 0.56" high LED
display with programmable decimal point.
METER MODES:
Run Mode The meter is in the run mode when the display is actively
showing a process.
Configuration Mode The meter is in the configuration mode when you press the
MENU button to enable meter configurations.

METER BUTTONS
T-RST button - Clears the tare value.
£/MAX button - In the run mode, press the £/MAX button to show the
maximum value if jumper S3 is installed: the meter momentarily shows
“####”, then flashes the maximum value encountered since the last peak
reset. Press the £/MAX button to show the VALLEY value if jumper S3 is
removed: the meter momentarily shows “™™™™”, then flashes the minimum
value encountered since the last valley reset. In the configuration mode, press
the £/MAX button to change the flashing digit’s value (increments by one).
£/TARE button - In the run mode, press the £/TARE button to tare the
display value to zero. In the configuration mode, press the £/TARE button to
scroll through available choices, or to move one digit to the right.
MENU button - In the run mode, press the MENU button to enable meter
configuration changes. Refer to specific procedure for more details.
RESET button - In the run mode, press the RESET button to reset the Peak
and Valley registers: the meter momentarily shows “PrSt” or “VrSt” , then
resets both values. In the configuration mode, press the RESET button twice
quickly to escape from the configuration mode.
