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 Meter with all applicable connectors attached.

1 Owner's Manual

1 Set Mounting brackets

1 QuickStart Manual

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.

SECTION 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 61010-1:2001, 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!

2.7 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 "D.RTD".

3.1 RATING/PRODUCT LABEL

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

3.2 MAIN BOARD POWER JUMPERS

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!

To check voltage jumpers, or to change from 115 V to 230 V ac:

1. Remove the main board from the case. Refer to Section 2.7.

2. Locate the solder jumpers W1, W2, and W3 (located near the edge of the

3. If your power requirement is 115 V ac, solder jumpers W1 and W3 should

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

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

3.2 MAIN BOARD POWER JUMPERS (Continued)

S2 jumpers are for sensor break indications:

* S2A jumper is not used
* S2B jumper is for positive sensor break on input 1 (i.e. heating)
* S2C jumper is for positive sensor break on input 2 (i.e. heating)
* S2D is not used

S3 jumpers are used for the following (refer to Table 3-1):

* To enable or disable the front panel push-buttons
* To allow for an extremely low resistance load for analog output
* To disable the MENU button
* To perform calibration procedure

Test pins TP1 - TP11 are for testing purposes. Do not use as reading errors may
result.

Table 3-1 S3 Jumper Functions

Jumper Description

S3-A Install to enable front panel push-buttons.

Remove to disable all front panel push-buttons
S3-B Removed. Install for factory calibration only.
S3-C Normally removed. Install for analog voltage output when load is less than

1 Kohm impedance. Care should be taken when installing this jumper.
S3-D Removed. Not used.
S3-E If installed without S3-B, the MENU button locks out.

While in run mode, if you press the MENU button, the display shows

“LOCK".

3.3 MOUNTING THE METER

Figure 3-3 Meter - Exploded View

1. Cut a hole in your panel, as
shown in Figure 3-3. For
specific dimensions refer to
Figure 3-4.

2. Insert the meter into the hole.
Be sure the front bezel gasket
is flush to the panel.

3. Slide on mounting bracket to
secure.

4. Proceed to Section 3.4 to
connect your sensor input
and main power.
