Performance Verification Tests
7
To prepare the Unit Under Test (UUT) for verification:
1. Visually inspect the UUT outer case for cracks or damage.
2. Open the battery compartment and inspect the battery and battery compartment for corrosion or damage.
3. Install a new AA battery prior to verification.
4. Close the UUT battery compartment door.
5. Set the UUT temperature units for degrees Celsius (°C) if necessary.
6. Push SEL until °C alone is shown. Change by pushing SET.
Performance Verification Test Procedures
Note
The subsequent verification test requires the blackbody emissivity to be set to 0.95 at all
temperature points.
Note
For temperatures below ambient, to reduce the chance of condensation or ice buildup on the
emitter plate of the 4180, it is recommended to install a clean dry air or nitrogen gas purge
box on the front of the 4180 Blackbody. Although the purge box is recommended, it is optional.
If temperature measurements are made without a purge box, refer to the 4180 User Manual
for how to make proper temperature measurements below ambient. See Figure 3.
