Before You Start
Safety Information
1 Before You Start
1.1 Introduction
The Reference Thermometers (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 thermometers are a handheld, battery operated
instrument that measures temperature using Platinum resistance Thermometers (PRT),
Thermistors, and Thermocouples (TC).
1.2 Standard Equipment
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 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 5.)
1.3 Safety Information
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 3.
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.
1
1523, 1524 Reference Thermometer
Safety Information
●
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 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.
●
On the 1524 model, thermocouples can only be used on channel 1.
1.3.2 Cautions
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.

1.4.1 EMC Directive
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.

1.4.2.2 For Use As a Benchtop Instrument (AC Adapter)
The instrument was tested to Immunity Requirements for Controlled EM Environments. Utilized in this state the instrument is designed to operate in a controlled
electromagnetic environment. The instrument experiences degradation in the presence
of strong elds in the frequency range of 150 to 200 MHz and we suggest that it not be
used in close proximity to VHF transmitters.
1.4.3 Locking out non SI units
Through a specic key-press sequence, the user can choose to disable the °C °F toggle
switch so that temperature is displayed in SI units only. Once the units toggle switch
has been locked, subsequent key presses will not allow temperature to be displayed in
°F.
Instructions for locking out non SI units (see illustration below)
1. Simultaneously press and hold down the °C °F key and the BACKLIGHT key,
press the POWER ON key
2. The display will read: SI units only ON
3. Release the °C °F and the BACKLIGHT key
