you connect it to a po er 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 t o 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 ( hich
is the factory setting) and the S4 jumper
must be installed ( hich 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, ill

2.4.3 Meter Cold-Junction Offset
Calibration procedure
This menu item ill allo 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 ill begin to flash and
automatically adjust the offset reading
on the display to 0.0 (± 0.1)

This automatic cold junction calibration
should be all that is necessary to calibrate
the CJ offset, ho ever if you ant 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 allo several seconds to let the
display stabilize. Press MENU to save and
activate the calibration. (Meter ill briefly
