Monitoring the Operating Temperature
The operating range for the APS devices to achieve the specified accuracy for readings is 15°C to
45°C. The APS can withstand exposure to 60 °C for brief periods. The Temperature monitor
in the APS device status bar of the ParticleSpectrum window (see Figure 3.23) shows the
current operating temperature of the APS device with a numeric readout and a color graphic.
Figure 3.23: Temperature Monitoring Gauge
The temperature bar changes color to indicate where the current temperature is relative to the
accurate operating range:
• Blue. Less than 15 °C; the APS device is operating below the range where it
produces accurate readings.
• Green. 15 °C to 45 °C; the APS device is operating in its optimum temperature
range, where it produces readings meeting the specified accuracy.
• Red. 45 °C to 80 °C and Greater than 80 °C; the APS device is operating at a temperature
so high that it might be damaged.
