1.2Safety Information
Use this instrument only as specified in this manual. Otherwise, the protection provided by the instrument may be impaired.
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.
1.2.1
Warnings
To avoid 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 500°C and the display reads 500°C, the target surface is 500°C.The top 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 polarized power cord.
•DO NOT connect this unit to a non-grounded, non-polarized outlet.
•HIGH VOLTAGE is used in the operation of this equipment. SEVERE INJURY OR DEATH may result if personnel fail to observe safety precautions. 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.
•This instrument is intended for indoor use only.

Safety Information
•Overhead clearance is required. DO NOT place this instrument under a cabinet or other 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 periods of time requires caution.
•Completely unattended high temperature operation is not recommended for safety reasons.
•Before initial use, after transport, and anytime the dry-well 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.
•The instrument can generate extreme temperatures. Precautions must be taken to prevent personal injury or damage to objects.
•Use only a grounded AC mains supply of the appropriate voltage to power the instrument. Refer to Section 3.1, Specifications for power details.
•The instrument is equipped with operator accessible system fuses. If a fuse blows, it may be due to a power surge or failure of a component. Replace the fuse once. If the fuse blows a second time, it is likely caused by failure of a component part. If this occurs, contact an Authorized Hart Scientific Service Center (see Section 1.3). Always replace the fuse with one of the same rating, voltage, and type. Never replace the fuse with one of a higher current rating.
•Follow all safety guidelines listed in the user’s manual.
•Calibration Equipment should only be used by Trained Personnel.
1.2.2
Cautions
•DO NOT plug the unit into 230V if the heater switches and fuse holder read 115V. This action will cause the fuses to blow and may damage the instrument.
•Components and heater lifetime can be shortened by continuous high temperature operation.
•DO NOT use fluids to clean the target surface.
•DO NOT change the values of the calibration constants from the factory 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.

9132 Portable IR Calibrator
User’s Guide
•Operate the instrument in room temperatures between 5 and 50°C. (41–122° F). Allow sufficient air circulation by leaving at least 6 inches of space between the instrument and nearby objects.
•The instrument is a precision instrument. Although is has been designed for optimum durability and trouble free operation, it must be handled with care. Always carry the unit in an upright position. The convenient fold-up handle allows one hand carrying. The instrument should not be operated in excessively wet, oily, dusty, or dirty environments. Do not operate near flammable materials.
•Before initial use, after transport, and anytime the dry-well has not been energized for a “dry-out” period of 1-2 hours before it can be assumed to meet all of the safety requirements of the IEC 1010-1.
•If a main supply power fluctuation occurs, immediately turn off the instrument. Wait until the power has stabilized before re-energizing the instrument.

2 Introduction
2 Introduction
The Hart Scientific 9132 Portable IR Calibrator may be used as a portable instrument or bench top temperature calibrator for calibrating point IR thermom-
eters. The 9132 is small enough to use in the field, and accurate enough to use in the lab. Calibrations may be done over a range of 50°C to 500°C (122°F to
932°F). Temperature display and setability resolution of the 9132 is 0.1 degrees.
The instrument features:
•Rapid heating and cooling
•Hand strap
•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 solid state relay (triac) driven heater.
For improved uncertainties, a 0.125" external reference thermometer may be used in the calibration probe hole at the top of the instrument. When using an external reference thermometer, the unit 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 9132 calibrator was designed for portability, low cost, and ease of operation. 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 described in this user guide.
