2 Introduction
The Fluke Hart Scientific 9133 Mid-Range Field IR Calibrator may be used as
a portable instrument or bench top temperature calibrator for calibrating
point IR thermometers. The 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°Cto150°C(-22°F to 302°F). Temperature display and setability resolu-
tion 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.
For improved uncertainties, a 0.125" diameter external reference thermome-
ter 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 tem-
perature may be easily set with the control buttons to any desired tempera-
ture within the specified range. The instrument’s multiple fault protection
devices insure user and instrument safety and protection.
The 9133 calibrator was designed for portability, low cost, and ease of oper-
ation. Through proper use, the instrument will provide continued accurate
calibration of temperature sensors and devices. The user should be familiar
with the safety guidelines and operating procedures of the calibrator as de-
scribed in this user guide.

4 Quick Start
4.1 Unpacking
Unpack the calibrator carefully and inspect it for any damage that may have
occurred during shipment. If there is shipping damage, notify the carrier
immediately.
Verify that the following components are present:
•9133 calibrator
•report of calibration
•power cord
•user's guide
•serial cable
•target cover
•9930 software
4.2 Set Up
Place the calibrator on a flat surface with at least 6 inches of free space
around the instrument. The prop may be swung down to raise the front of
the instrument from a horizontal position. Plug the power cord into a
grounded mains outlet. Observe that the nominal voltage corresponds to
that indicated on the back of the calibrator.
Turn on the power to the calibrator by toggling the power switch on. The
fan should begin quietly blowing air through the instrument and the con-
troller display should illuminate after 3 seconds. After a brief self-test the
controller should begin normal operation. If the unit fails to operate please
check the power connection.
The thermal electric devices will start operating to bring the temperature of
the calibrator to the set-point temperature and the display will begin to
show the actual target temperature.
Caution: Use the target cover at temperatures below 5°C. If ice forms on
the target, the IR probe will not indicate the correct temperature.
4.3 Power
Plug the instrument power cord into a mains outlet of the proper voltage,
frequency, and current capability. Refer to Section 3.1, Specifications for
power details. Turn the instrument on using the rear panel “POWER”
switch. The instrument turns on and begins to heat to the previously pro-
13

grammed temperature set-point. The front panel LED display indicates the
actual instrument temperature.
4.4 Setting the Temperature
Section 8.2 explains in detail how to set the temperature set-point on the
calibrator using the front panel keys. The procedure is summarized here.
1. Press the “SET” button twice to access the set-point value.
2. Press the “UP” or “DOWN” button to change the set-point value.
3. Press the “SET” button to program in the new set-point.
4. Press the “EXIT” button to return to the temperature display.
When the set-point temperature is changed the controller switches the
heater on or off to raise or lower the temperature. The displayed tempera-
ture gradually changes until it reaches the set-point temperature. The tar-
get may require 5 to 10 minutes to reach the set-point depending on the
span. Another 5 to 10 minutes is required to stabilize within ±0.1°Cofthe
set-point. Ultimate stability may take 15 to 20 minutes more of stabilization
time.
