1.1 Before You Begin

If you need assistance, please contact the
Customer Service Department nearest
you.

Remove the packing slip and verify that
you have received everything listed,
including:

1 Indicator/controller with all applicable

connectors attached

1 Owner’s 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.

Inspect the container and equipment for
signs of damage as soon as you receive
the shipment. Note any evidence of
rough handling in transit. Immediately
report any damage to the shipping
agent. The carrier will not honor
damage claims unless all shipping
material is saved for inspection. After
examining and removing the contents,
save the packing material and carton in
the event reshipment is necessary.

In addition to the meter and connectors,
you will need the following items to setup
your unit:

115VAC three-prong power cord

Features

1.3 Safety Considerations

The unit is protected in accordance with
Class II of IEC 348 and VDE 0411.
Remember that the unit has no power-on
switch. It will be in operation as soon as
you connect it to a power source.

Do not expose the unit to rain or moisture.
Do not operate your unit in flammable or
explosive atmospheres. As with any
electronic instrument, you may encounter
high voltage exposure when installing,
calibrating, or removing parts. Be careful
when working near conductors carrying
large currents. Use twisted-pair
connections to the unit. Use magnetic
shielding materials, or move the unit away
from the current source to reduce
magnetic field problems. Do not exceed
power rating on label located on the top of
the controller housing. Failure to follow

all instructions and warnings may result
in injury!

2.1 Introduction

The unit has two different modes of
operation. The first, Run Mode, is used to
display process value and display or clear
peak and valley values. The other mode,
Configuration Mode, is used to navigate
through the menus options and configure
the meter.

The S51 jumper must be removed (which
is the factory setting) and the S4 jumper
must be installed (which is not the factory
setting) for all menu configuration options
to be available. (See page 34 for further
jumper information.)

This part of the manual, Operation, will
explain both the Run Mode and the
Configuration Mode and is divided into
the following sections:

The unit can display temperatures in 1° or

0.1° resolution. When using type R or S

the meter will only be indicating with 1°
resolution. The DEc.P menu item will not
be available for these two types of
thermocouples.

2.4.3 Meter Cold-Junction Offset
Calibration procedure

This menu item will allow you to adjust the
cold junction offset calibration.

1. Press MENU until meter flashes:

C.J. Z (cold junction zero)

2. Connect the proper thermocouple to
the input at J4 and using a
thermocouple calibrator apply 0.0°C.

3. Press /MAX to display the cold-
junction offset. (If the meter reading at
this point is more than 5.0 recheck your
Thermocouple connections and make
sure 0.0°C is applied.)

4. The Cold-junction calibration on the
unit is semi-automatic. Press MENU to
activate the internal compensation. The
display will begin to flash and
automatically adjust the offset reading
on the display to 0.0 (± 0.1)

OPERATION

15

This automatic cold junction calibration
should be all that is necessary to calibrate
the CJ offset, however if you want to
additionally adjust the offset manually, the
/MAX and /MIN buttons at this point
can be used to manually increase (/MAX)
or decrease (/MIN) the display 0.1° each
time /MAX or /MIN is pressed. After
each press allow several seconds to let the
display stabilize. Press MENU to save and
activate the calibration. (Meter will briefly
display Stor.)

The following menu items will only be
available with S4 installed.

menu will affect the meter’s calibration
and should only be performed by
qualified personnel with accurate test
equipment.

2.4.5.1 Meter SPAN calibration
procedure

This item will only be available if the S4
jumper, which enables the calibration
configuration, is installed!

The Span calibration does not require any
special compensated thermocouple wires at
the input terminals. Standard copper wire
hooked up to a mV calibration source is
required.
