fi eld. When the UP/DOWN control appears (right),

Setting the Oven Temperature Limit

A mechanical thermostat is integrated with the temperature control circuit
for fail-safe temperature control. This thermostat should be used to prevent
accidental overheating of low temperature permeation devices or permeation
devices containing toxic or hazardous chemicals. Overheating can rupture the
device or cause an unintended release of chemicals.

The temperature markings on the front panel are approximate (±10°C). For a
more accurate setting:

1. Using a fl at-tipped screw driver or the tool provided, adjust the setting all the

way clockwise.

2. Turn on the Dynacalibrator main power. Do not install any permeation

devices yet.

3. Set the chamber temperature 5°C higher than the desired operating temperature,

and wait for the status indicator to change from red to green, indicating that
the chamber has equilibrated.

4. Once thermal equilibrium is achieved, slowly adjust the setting clockwise until

the touch screen displays a box indicating “PFAIL”. (you may hear a faint click.)
