THERMOCOUPLE CALIBRATOR

USER MANUAL

The T/C calibrator is a handheld unit for thermocouple
(T/C) measurement or simulation. Eight T/C types are
supported referencing NIST175 and ITS90 standards.
Temperature can be displayed in selectable engineering
units of ºC, °F, ºR, K and mV.

Introduction

The Thermocouple (T/C) calibrator has been designed using the latest
technology to provide reliable accuracy throughout its entire operating
temperature range, dependable operation, and exceptional battery life.

The compact design makes the unit easy to carry and the intuitive user
interface makes it easy to use.

Temperature measurements/simulations are displayed on a large, easy-to-read
liquid crystal display (LCD). This unit has two backlights: a green backlight
which is user activated to improve readability in low light conditions, and an
automatic red backlight which indicates an over-range condition.

Twelve keys provide access to the functional modes and menus, including
Measure, Simulate, Setup, Run, Record, Edit, and Backlight activation. A list
of these functions is p

nted on the back of the case.

Keypad Functions

ON/OFF Key

The ON/OFF key, represented by the standard ON/OFF symbol,
turns the unit ON or OFF (note: the ON/OFF key must be held until the
display turns on or off). Upon power on, the unit will perform a self-test,
displaying all segments for approximately 1-2 seconds, then go into the mode
in use when unit was powered off. The firmware version is displayed at the
end of the self-test.

BACKLIGHT Key

symbol, turns the green display backlight on and off. The backlight will
remain on for approximately 20 seconds if not manually turned off. To
override the auto shut off timer, press and hold the BACKLIGHT key to turn
the backlight on. After holding the key for approximately 2 seconds, the
backlight will flash off and back on. Release the key now and the backlight
will remain on until manually turned off or until power is cycled.

SETUP Key

The UNITS function is only available when the unit is actively measuring or
simulating temperature signals. This key is also used to go back one menu
item in SETUP or back to the previous recorded value while in VIEW mode.

selections when EDIT icon is lit. The keys are also used to increment numeric
values. For this function, the narrow band signifies fine adjustment, the
medium band signifies medium adjustment, and the wide band signifies coarse
adjustment for changing the values. The positive sign (+) indicates the Group
Keys will increment the displayed value.

decrement numeric simulation values. For this function, the narrow band
signifies fine adjustment, the medium band signifies medium adjustment, and
the wide band signifies coarse adjustment for changing the values. The
negative sign (-) indicates the Group Keys will decrement the displayed value.

In addition, when the narrow band and wide band areas are pressed
simultaneously (HOME) the unit will return to the Measure mode default
position.

Liquid Crystal Display (LCD)

The LCD displays:

• current Functional Mode and/or state via icons along top of display

• primary measurements via the large middle segments

• menu items and additional information via the bottom alpha-numeric

segments

The LCD incorporates two backlights:

• a green backlight which is user activated via the BACKLIGHT key

• a red backlight which is automatically activated during an over-

range/under-range condition.

Functional Modes and States

The unit supports measurement and simulation activities using the following
Functional Modes:

1. Measure - temperature units or measure mV; MEAS icon shown at
top of display

2. Simulate, Manual - simulate fixed values of temperature units or
mV; SIM icon shown at top of display

3. Simulate, Auto - simulate step or ramp output functions in
temperature units or mV; SIM icon shown at top of display

Each Functional Mode has three possible States:

1. Run - active measurement or simulation; MEAS or SIM icon
shown at top of display

2. Setup – access navigation menus; MEAS & SETUP or SIM &
SETUP icons shown at top of display

3. Edit Setup - edit a parameter within a navigation menu; “EDIT

EAS & SETUP” or “EDIT, SIM & SETUP” icons shown at top

M
of display

The T/C calibrator will power up in its previous functional mode when turned
ON. Example: if previous use was SIM (Auto), then next power up will
default to SIM (Auto). Simulation will restart when user confirms the desired
setup and presses the ENTER key (two times).

Record Mode

The T/C calibrator can store up to 240 temperature measurements in a single
record (REC) session. For maximum flexibility, a REC session can be:

• Automatic - the current value is automatically stored every 5 seconds, for
up to 20 minutes.

• Manual - the current value is stored every time the Enter key is pressed, up
to 240 times.

Both types of REC sessions can store between 1 and 240 measurements. The
measurement data is preserved in non-volatile memory until another REC
session is started.

Certification

The T/C calibrator is EMI/ESD compliant to the test specification EN61326.
The unit is for general purpose use only. Do not use in potentially hazardous
atmospheres.

Changing the Batteries

The T/C calibrator is powered by three, 1.5 volt AA size batteries. The “BAT”
icon in upper left of display will activate when battery output drops below a
threshold level. Approximately 2 hours of life remain from that point.

Replace all three AA batteries at the same time for best performance.

To replace the batteries, locate the battery compartment at the lower rear of
the unit. Remove the screws located at the top center and bottom center of the
battery cover by turning them coun

te

rclockwise until fully disengaged from

the base. Remove the cover. Do not remove the pink anti-static foam that is

attached to the inside of the battery cover. This foam is necessary to
properly secure the batteries under specified shock and vibration
conditions.

Remove the batteries by pulling the positive side first straight out of the
battery compartment. Note the positive (+) and negative ( – ) battery polarity
markings at the bottom of the compartment, as shown below.

Install the three batteries by sliding them into the bottom of the battery slots,
positive (+) end first, making sure the polarity markings on the batteries align
with the markings molded into the battery compartment. When a battery is
installed with the polarity reversed, the stand-offs prevent the negative battery
terminal from contacting the positive terminal in the battery compartment.
The unit will not power up in this condition; to correct, simply reverse the
battery to correct the polarity.

With the batteries secured in the battery compartment, replace the
compartment cover. The cover has only one orientation for correct alignment.
