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 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.

•

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.

Never introduce any foreign material onto the surface plate. Fluids, etc.

•

can leak into the instrument causing damage.

• 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 instrument should
not be operated in excessively wet, oily, dusty, or dirty environments. Do
not operate near flammable materials.

2 Introduction

2 Introduction

Hart Scientific’s Model 3125 Detachable Hot Plate is controlled by Hart Scien
tific’s 2200 controller and uses a precision platinum RTD as a sensor with a
heater to control the temperature. The 3125 and 2200 are a matched set.

The controller display shows the temperature and also the set-point tempera

­ture. The temperature may be set to any temperature within the range of 35°C
to 400°C in 0.01°C or °F increments by using the buttons on the control panel.
The controller’s multiple fault protection devices insure user and instrument
safety and protection.

The Detachable Hot Plate (see Figure 1) consists of a controlled plate made of
aluminum. A heater is attached to the bottom with an RTD temperature sensor
used to control it. The housing consists of a top cover and a base, which serve
as a clamp and strain relief point for the wiring. The Reference Well is avail

­able for use with a 3/16-inch diameter probe, which may be used to check the
plate temperature. This well is used to calibrate the system.

4.1 Troubleshooting Problems, Possible Causes,
and Solutions

In the event that the instrument appears to function abnormally, this section
may help to find and solve the problem. Several possible problem conditions
are described along with likely causes and solutions. If a problem arises, please
read this section carefully and attempt to understand and solve the problem. If
the problem cannot otherwise be solved, contact an Authorized Service Center
(see Section 1.3). Be sure to have the model number, serial number, and voltage
of your instrument available.

Problem Possible Causes and Solutions

Incorrect temperature
reading

Incorrect R0, ALPHA, and DELTA parameters. Find the values for R0, AL
PHA, and DELTA on the Report of Calibration that was shipped with the instru
ment (or from subsequent calibrations of the instrument). Reprogram the
parameters into the 2200 memory (see the 2200 User’s Guide). Allow the in­strument to stabilize and verify the accuracy of the temperature reading.

Controller locked up. The controller may have locked up due to a power
surge or other aberration. Initialize the system by performing the Factory Reset
Sequence.

slowly

Factory Reset Sequence. Hold the SET and EXIT buttons down at the same
time while powering up the instrument. After the instrument displays
release the buttons. The display shows
displays the firmware version. After performing the master reset sequence, all
of the configuration parameters are reset to their default values. Reprogram the
R0, ALPHA, and DELTA parameters into the Model 9132 memory (see Section
, Calibration Parameters) and any other applicable configuration parameters.
Allow the instrument to stabilize and verify the accuracy of the temperature
reading.

Blown fuse. A fuse may have blown due to a power surge or failure of a com
ponent. Replace the fuse once. If the fuse blows a second time, it is likely
caused by the failure of a component. Always replace the fuse with one of the
same rating, voltage, and type. Never replace the fuse with one of a higher cur
rent rating.

Incorrect scan and scan rate settings. The scan and scan rate settings may
be set to unwanted values. Check the Scan and Scan Rate settings. The scan
may be off (if the unit seems to be responding too quickly). The scan may be
on with the Scan Rate set low (if unit seems to be responding too slowly).
