1.2 Safety Information

Use this instrument only as specified in this manual. Otherwise, the pro
tection provided by the instrument may be impaired. Refer to the safety
information in Warnings and Cautions.

The following definitions apply to the terms “Warning” and “Caution”.

•

“Warning” identifies conditions and actions that may pose hazards to
the user.

•

“Caution” identifies conditions and actions that may damage the in­strument being used.

Warnings

To avoid possible electric shock or personal injury, follow these guide­lines.

BURN HAZARD – DO NOT touch the IR target surface of the unit.

The temperature of the IR target surface is the same as the actual
temperature shown on the display. If the unit is set at 150°C and the
display reads 150°C, the target surface is at 150°C.

Temperatures above 70°C (158°F) are considered hazardous. Use ex
treme care when working with these temperatures. Observe all warn
ings and cautions given in this manual.

The sheet metal of the instrument may exhibit extreme temperatures
for areas close to the IR target surface.

-

-

-

-

-

DO NOT turn off the unit at temperatures higher than 100°C. This
could create a hazardous situation. Select a set-point less than 100°C
and allow the unit to cool before turning it off.

DO NOT operate this unit without a properly grounded, properly polar
ized power cord.

DO NOT connect this unit to a non-grounded, non-polarized outlet.

1 Before You Start

HIGH VOLTAGE is used in the operation of this equipment. SEVERE
INJURY OR DEATH may result if personnel fail to observe safety pre

cautions. Before working inside the equipment, turn the power off and
disconnect the power cord.

Always replace the fuse with one of the same rating, voltage, and type.

Allow at least six inches of space between the instrument and nearby
objects. DO NOT place instrument under a flammable structure.

DO NOT use this unit for any application other than calibration work.

DO NOT use this unit in environments other than those listed in the

user’s guide.

DO NOT operate near flammable materials.

-

Use of this instrument at HIGH TEMPERATURES for extended peri
ods of time requires caution.

Completely unattended high temperature operation is not recom
mended for safety reasons.

Before initial use, after transport, and anytime the instrument has not
been energized for more than 10 days, the calibrator must be ener­gized for a dry-out period of 1 to 2 hours before it can be assumed to
meet all of the safety requirements of the IEC1010-1.

This instrument is intended for indoor operation only.

Follow all safety guidelines listed in the user’s manual.

Calibration Equipment should only be used by Trained Personnel.

-

-

Cautions

To avoid possible damage to the instrument, follow these guidelines.

Use the target cover at temperatures below 5°C. If ice forms on the tar
get, the IR probe will not indicate the correct temperature.

DO NOT use fluids to clean out the target surface.

DO NOT change the values of the calibration constants from the fac

tory set values. The correct setting of these parameters is important to
the safety and proper operation of the calibrator.

DO use a ground fault interrupt device.

2 Introduction

The Hart Scientific Model 9133 Mid-Range Field IR Calibrator may be
used as a portable instrument or bench top temperature calibrator for cal
ibrating point IR thermometers. The Model 9133 is small enough to use
in the field, and accurate enough to use in the lab. Calibrations may be
done over a range of -30°C to150°C (-22°F to 302°F). Temperature dis
play and setability resolution of the 9133 is 0.1 degrees.

The instrument features:

•

Rapid heating and cooling

•

RS-232 interface capability

Built in programmable features include:

•

Temperature scan rate control

•

Eight set-point memory

•

Adjustable readout in °C or °F

The temperature is accurately controlled by Hart’s digital controller. The
controller uses a precision platinum RTD as a sensor and controls the
well temperature with a FET driven thermal electric device.

2 Introduction

-

-

For improved uncertainties, a 0.125" diameter external reference ther­mometer may be used in the calibration probe hole at the top of the in­strument. When using an external reference thermometer, the instrument
accuracy, stability, and ambient temperature effects on the surface can
be minimized.

The LED front panel continuously shows the current temperature. The
temperature may be easily set with the control buttons to any desired
temperature within the specified range. The instrument’s multiple fault
protection devices insure user and instrument safety and protection.

The Model 9133 calibrator was designed for portability, low cost, and
ease of operation. Through proper use, the instrument will provide con
tinued accurate calibration of temperature sensors and devices. The
user should be familiar with the safety guidelines and operating proce
