4 Quick Start
make sure the valve is closed. See Section 5.3, Bath Preparation and Filling. Be
sure to place the bath in a safe, clean and level location.
Fill the bath tank with an appropriate liquid. Be sure to select the correct fluid
for the temperature range of the calibration. Bath fluids should be selected to
operate safely with adequate thermal properties to meet the application require-
ments. For operation at moderate bath temperatures, clean distilled water works
well. Carefully pour the fluid into the bath tank through the large rectangular
access hole above the tank avoiding spilling any fluid. The fluid must not ex-
ceed a height of 12.7–20.3 mm (0.5–0.8 inches) below the bottom of the lid
(
NOT
the access cover).
Note: As the temperature of the bath increases the fluid level will increase, see
Section 7.1.5 on page 24.
4.3 Power
Plug the bath power cord into a mains outlet of the proper voltage, frequency,
and current capability. Refer to Section 3.1, Specifications, for power details.
Refer to and read the CAUTION at the front of the manual concerning brown-
out and over voltage protection.
Check the back panel label for the correct
voltage and frequency prior to energizing the unit.
Turn the bath on using
the front panel “POWER” switch. The bath will turn on and begin to heat or
cool to reach the previously programmed temperature set-point. The front panel
LED display will indicate the actual bath temperature. Set the cooling switch to
“ON” for below or near ambient temperatures.
Note:
The actual temperature where cooling is required depends on the bath
fluid and whether a cover is used over the access well.
4.4 Setting the Temperature
In the following discussion and throughout this manual a solid box around the
word SET, UP, DOWN or EXIT indicates the panel button to press while the
dotted box indicates the display reading on the front panel. Explanation of the
button function or display reading is written at the right.
To view or set the bath temperature set-point proceed as follows. The front
panel LED display normally shows the actual bath temperature.

When “SET” is pressed the display shows the set-point memory that is cur-
rently being used and its value. Eight set-point memories are available.
