Preparing for the Performance Test
XWWarning
To avoid possible electric shock or personal injury:
• Do not perform the following procedures unless qualified to do so. Some
procedures involve the use of high voltages.
• Before handling the test connections and in between tests, make sure the
calibrator is in standby mode (STBY).
To prepare for the performance test:
1. Make sure that you have the required equipment (refer to Table 1).
2. Warm up the calibrator as required by its specifications.
3. Allow the temperature of the UUT to stabilize at room temperature ( 23 °C ± 5 °C [73 °F ± 9 °F] ).
4. Check the fuses and Battery, and replace them if necessary. Refer to "Testing the Fuses”, “Replacing
the Fuses", and "Replacing the Battery".
