Probes may be very hot when removed from the instrument. Cautiously handle probes to prevent personal injury. Carefully place probes on a heat resistant surface or rack until they are at room temperature. Never place any objects other than the probe to be calibrated into the plate.

2 Introduction 2 Introduction Hart Scientific’s Model 9135 Infrared Thermometer Calibrator is a small, portable instrument designed for quick on-site checks and calibration of infrared thermometers. It features an aluminum temperature-controlled plate coated with special 0.95 emmisivity paint. A precision proportional-integral temperature controller maintains the temperature of the plate. The set-point can be conveniently selected by the one-button control to 50°C, 100°C, or 150°C.

9135 Infrared Thermometer Calibrator User’s Guide 3.3 Warranty Fluke Corporation, Hart Scientific Division (Hart) warrants this product to be free from defects in material and workmanship under normal use and service for a period as stated in our current product catalog from the date of shipment.
4 Quick Start Unpacking 4 4.1 Quick Start 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: • 9135 Calibrator • Manual • Report of Calibration • Calibration Label 4.2 Set-up Place the calibrator on a flat surface with at least three inches of free space around the instrument.
9135 Infrared Thermometer Calibrator User’s Guide The mains supply must be reasonably stable and free from surges, dropouts, and interference that can affect the temperature stability of the IR target.
5 Parts and Controls Back Panel 5 Parts and Controls The user should become familiar with the 9135 calibrator and its parts. Refer to Figures 1 and 2 as you read the following sections. 5.1 Back Panel Power Cord - The power cord attaches to the back of the instrument. It plugs into a standard 115 VAC (optional 230 VAC) grounded socket. Power Switch - The power switch is located on the back panel of the calibrator. The switch is either on or off. The on position is for normal operation.

6 General Operation Set-up 6 General Operation This section explains basic operation of the 9135 calibrator. 6.1 Set-up Place the calibrator on a flat surface with at least three inches of free space around the instrument. The prop may be swung down to tilt the instrument from a horizontal position. Plug the power cord into a grounded mains outlet. Make sure the supply voltage and voltage switch settings are correct (see Section 4.3).
7 Controller Operation 7 Controller Operation The 9135 calibrator uses a precise analog proportional-integral controller that maintains the temperature of the IR target. The set-point is controlled by a special digital switching circuit that allows one button to advance through the sequence of set-points. It also contains a power on reset circuit that causes the controller to default to the first set-point immediately after the power is switched on.
8 Thermometer Calibration IR Thermometer Calibration 8 Thermometer Calibration The 9135 calibrator was designed primarily for calibrating infrared thermometers. However, it can also be used to calibrate certain types of RTDs. The following sections explain the calibration of IR thermometers and RTDs respectively. 8.1 IR Thermometer Calibration Infrared thermometers are calibrated by pointing them at the 9135’s IR target and comparing their readings to the known temperature of the target.
9135 Infrared Thermometer Calibrator User’s Guide bration. DO NOT attempt to calibrate thermometers unless the green ready LED is lit, otherwise accuracy may be compromised. • The 9135’s test well is intended for 3.18 mm. (0.125") diameter probes only. DO NOT attempt to force probes larger than this size or bent probes into the well. For good accuracy the probe must be inserted the full depth of the well and not fit too loosely.
9 Calibration Procedure 9 Calibration Procedure The 9135 should be calibrated regularly to ensure accuracy. A one-year or less calibration interval is recommended. Calibration should only be performed by a qualified and authorized technician. The calibration of the 9135 entails adjusting the calibration potentiometers inside the instrument until the temperature of the IR target is close to the set-point temperature as observed with a calibrated standard RTD at each of the three set-points.
10 Maintenance 10 Maintenance • This calibration instrument has been designed for a minimum of required maintenance as long as it is handled with proper care. Please regard the following: • Avoid operating the instrument in an oily, wet, dirty, or dusty environment. If the outside of the instrument becomes soiled, it may be wiped clean with a damp cloth and mild detergent. DO NOT use harsh chemicals on the surface which may damage the paint. • It is very important to keep the IR target clean.
9135 Infrared Thermometer Calibrator User’s Guide WARNING: Never introduce any fluids or other foreign material onto the IR target or into the well block. This will damage the calibrator, cause loss of accuracy, and may cause sticking and damage to your probes. In the event that the calibrator should require service or repair, please contact a Hart Scientific Authorized Service Center for assistance. The user should not attempt to make any repairs or adjustments.
11 Troubleshooting CE Comments 11 Troubleshooting If problems arise while operating the 9135, this section provides some suggestions that may help you solve the problem. If, after considering the following suggestions, the problem still cannot be resolved, call an Authorized Service Center for assistance. Opening the unit without contacting an Authorized Service Center may void the warranty.
