When the “Buzzer” is switched -Off- the alarm conditions will be announced only with the relevant -HAL- or -LAL- message on the display.

10.7OSP 500/800 decimal point selection

NOTE: THIS FEATURE WORKS ON OSP 500 OR OSP800 WITH FIRMWARE FROM VERSION 4.001.

It is possible to display the temperature measured with a decimal digit.

The following procedure is used to enable the operating mode.

"Switch the instrument off.

"Keep pressed <*>+<SEL> keys and switch the unit on by pressing the <Trigger> key. The temperature measurements will be displayed with the decimal digit.

Repeat the above procedure to disable the operating mode.

10.8Ambient Temperature Compensation (TAM)

This function is used to compensate the measure from the ambient temperature.

Targets which have low emissivity will reflect energy from their surrounding environments, which is going to add to their own emitted energy. If the temperature of the surrounding environment is the same value as the internal temperature of the unit, there is no need to consider this value as it is automatically and continually measured. However, in some industrial situations the surrounding environment (machines, furnaces, or other heat sources) has a much higher value than the one of the internal of the unit temperature. The table below "Effect of TAM on Accuracy" underlines these effects on measurement accuracy, with and without the use of the Ambient Temperature Compensation mode.

The Ambient Temperature Compensation mode should be used whenever the stated following points are true :

1.The target has a low emissivity.

2.Temperatures of objects facing targets are much hotter than the temperature of the unit.

3.An increased measurement accuracy is required
