Standard Equipment
Before You Start1
Introduction1.1
The Reference Thermometer Readouts (1523, 1524) are designed to be reliable, stable, temperature measuring instruments that can be used in the eld or laboratory. They offer accuracy, portability, and speed for nearly every eld calibration application. The instruments have been designed with the eld user in mind and are
easy to use while maintaining stability, uniformity, and accuracy comparable to some laboratory instruments.
Your Fluke 1523 and 1524 thermometer readout is a handheld, battery operated instrument that measures temperature using Platinum resistance Thermometers (PRT), Thermistors, and Thermocouples (TC).
Standard Equipment1.2
Unpack the instrument 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:
1523/1524 Reference Thermometer Readout with 3 AA batteries
AC Adapter, with power cord
RS-232 Cable
User’s Guide
Documentation CD
Report of Calibration and calibration label
Clamp-on ferrite(s)
If all items are not present, contact an Authorized Service Center. (See Section 1.8, Authorized Service Centers on page 7.)

Safety Information
Safety Information1.3
The Reference Thermometer is designed in accordance with EN 61010-1 {2nd Edition}, and CAN/CSA 22.2
No 61010.1-04. Use this instrument only as specied in this manual, otherwise the protection provided by the
instrument may be impaired.
A Warning identies conditions and actions that pose hazard(s) to the user; a Caution identies conditions
and actions that may damage the instrument being used.
International symbols used on the reference thermometer and in this manual are explained in Table 1 on page
4.
1.3.1 Warning
To avoid possible electric shock or personal injury:
Do not use the reference thermometer in environments other than those listed in the user’s guide.
Do not use the reference thermometer for any application other than that which is specied. The
instrument was designed for temperature measurement and calibration. Any other use of the instrument
may cause unknown hazards to the user.
If the reference thermometer is used in a manner not in accordance with the equipment design, the
operation and the protection provided by the instrument may be impaired. In addition, safety hazards
may arise.
Do not apply more than the rated voltage, as marked on the reference thermometer, between the inputs,
or between any input and earth ground (30 V, 24 mA max all terminals).
Follow all equipment safety procedures.
Calibration equipment should only be used by trained personnel.
The reference thermometer is intended for indoor use only.
Before you use the instrument, inspect the case. Look for cracks or missing plastic. Pay particular
attention to the insulation surrounding the connectors. Do not use the reference thermometer if it

Safety Information
appears damaged or operates abnormally. Protection may be impaired. When in doubt, have the
instrument serviced.
Always use an isolated RTD or PRT (metal sheath isolated from lead wires).
Make sure the battery door is closed and latched before you operate the reference thermometer.
Do not operate the reference thermometer around explosive gas, vapor, or dust.
For battery operation use only 3 AA batteries, properly installed in the reference thermometer case.
1524 model, thermocouples can only be used on channel 1.
Cautions1.3.2
To avoid possible damage to the reference thermometer or to equipment under test:
Do not apply more than the rated voltage, as marked on the reference thermometer, between the inputs,
or between any input and earth ground (30 V 24 mA max all terminals).
Unless recalibrating the instrument 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 instrument.
The instrument and any thermometer probes used with it are sensitive instruments that can be easily
damaged. Always handle these devices with care. DO NOT allow them to be dropped, struck, stressed,
or overheated.
DO NOT operate this instrument in an excessively wet, oily, dusty, or dirty environment.
Use the proper probes, function and range for your measurement.
Ensure probe coefcients are downloaded.

Using Clamp-On Ferrites
CE Comments1.4
EMC Directive1.4.1
Hart Scientic’s equipment has been tested to meet the European Electromagnetic Compatibility Directive
(EMC Directive, 2004/108/EC ). The Declaration of Conformity for your instrument lists the specic standards to which the unit was tested.
The instrument was designed specically as a test and measuring device. Compliance to the EMC directive is through EN 61326-1:2006 Electrical equipment for measurement, control and laboratory use – EMC
requirements
As noted in the EN 61326-1, the instrument can have varying congurations. The instrument was tested in a
typical conguration with shielded RS-232 cables.
Immunity Testing1.4.2
The instrument was tested to the requirements for laboratory locations.
Using Clamp-On Ferrites1.5
Clamp-on ferrites are provided for use in improving the instrument’s electromagnetic (EM) immunity in environments of excessive EM interference, like areas of heavy industrial equipment. We recommend placing the
ferrites on the cables of probes attached to the instrument.
To attach a ferrite to a probe cable, make a loop in the cable near the connector and clamp the ferrite around
half of the loop as shown in the diagram. The ferrite can be easily detached and moved to a new probe when
needed. (See Figure 1 on next page.)
