
The temperature is accurately controlled by Fluke’s digital controller. The control-
ler uses a precision platinum RTD as a sensor and controls the well temperature with
transistor driven thermoelectric devices.
The LED front panel shows the current well temperature. The temperature may be set,
using the control buttons, to any desired temperature within the instrument’s range.
Multiple fault protection devices insure user and instrument safety and protection.
This dry-well calibrator was designed for portability, low cost, and ease of operation.
Through proper use and maintenance, 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 the instruc-
tion manual.

Set-up3.2
Place the calibrator on a at surface with at least 6 inches of free space around the
instrument. Always leave enough clearance in front of the instrument to allow for
safe and easy insertion and removal of probes. The prop stand may be swung down to
raise the front of the instrument from a horizontal position. Plug the power cord into a
grounded mains outlet. Observe that the nominal voltage corresponds to that indicated
on the calibrator.
Turn on the power to the calibrator by toggling the power switch on. The fan should
begin quietly blowing air through the instrument and the controller display should
illuminate after 3 seconds. After a brief self-test the controller should begin normal
operation. If the unit fails to operate, check the power connection.
The display should show the well temperature and the well heater will bring the tem-
perature of the well to the set-point temperature.
After using the calibrator, allow the well to cool by setting the temperature to 25°C
and waiting 1/2 hour before turning the instrument off.
AC Power Operation3.3
Plug the dry-well power cord into a mains outlet of the proper voltage, frequency, and
current capability. Refer to Section 3.1, Specications, for the power details. Turn the
dry-well on using the switch on the rear panel. The dry-well will turn on and begin to
heat to the previously programmed temperature set-point. The front panel LED display
will indicate the actual dry-well temperature.

Setting the Temperature3.5
Section 6.2, Temperature Set-point, on page 19 explains in detail how to set the
temperature set-point on the calibrator using the front panel keys. The procedure is
summarized here.
Press “SET” twice to access the set-point value.1.
Press2. uor darrow to change the set-point value.
Press “SET” to program in the new set-point.3.
Press and hold “EXIT” to return to the temperature display.4.
When the set-point temperature is changed the controller switches the well heater
on or off to raise or lower the temperature. The displayed well temperature gradu-
ally changes until it reaches the set-point temperature. The well may require 5 to
10 minutes to reach the set-point depending on the span. Another 5 to 10 minutes is
required to stabilize within ±0.1°C of the set-point. Ultimate stability may take 15 to
20 minutes more of stabilization time.
