Set the Temperature
Temperature Set-point explains how to set the calibrator temperature set-point with the front panel
keys. Briefly, the procedure is:
1. Push SET twice to access the set-point value.
2. Push UP or DOWN to change the set-point value.
3. Push SET to store the new set-point.
4. Push EXIT to return to the temperature display.
When the set-point temperature changes, the heater switches on or off to raise or lower the
temperature. The well temperature gradually changes until it reaches the set-point temperature. The
well can require 25 minutes to reach the set-point, depending on the span. Another 10 minutes to 15
minutes is required to stabilize within ±0.03 °C of the set-point. Ultimate stability can take 20 minutes to
30 minutes more of stabilization time.
Bath Use
Read this section before you place the bath in service.
The information in this section is for general information only. Do not use this section as the basis for
calibration laboratory procedures. Each laboratory must write their own specific procedures.
Generally, baths are set to one temperature and used to calibrate probes only at that single
temperature. This means that the type of bath fluid does not have to change. Additionally, leave the
bath energized to reduce the stress on the system.
Select the correct fluid for the temperature range of the calibration. You must select bath fluids to
operate safely with adequate thermal properties to meet the application requirements. Be aware that
some fluids expand and could overflow the bath if not watched, see Bath Fluid and its subsections for
information specific to fluid selection and see the MSDS sheet specific to the fluid selected.
W Warning
To prevent possible fire, or personal injury:
• Use care to prevent personal injury or damage to objects. The bath generates extreme
temperatures.
• Carefully place probes on a heat/cold resistant surface or rack until they are at room
temperature. Probes can be extremely hot or cold when removed from the bath.
• Wipe the probe with a clean, soft cloth or paper towel before you insert it into another
bath. This prevents the contamination of fluids from one bath to another.
• Be aware that cleaning the probe can be dangerous if the probe has not cooled to
room temperature. Additionally, high temperature fluids can ignite the paper towels if
the probe has not been cooled.
• Be aware some of the high temperature fluids react violently to water or other liquid
mediums.
