6、.O. 33K1-4-1968-1 2 WARNING Unless otherwise designated, and prior to beginning the Calibration Process, ensure that all test equipment voltage and/or current outputs are set to zero (0) or turned off, where applicable. Ensure that all equipment switches are set to the proper position before making

7、connections or applying power. 3.2 Ensure that TI is properly grounded, connect all case grounds to facility ground. WARNING This procedure involves voltages that are hazardous to personnel. All necessary precautions during the conduct of these tests must be observed. 3.3 Connect TI and test equipme

8、nt to 115 V/60 Hz power, set POWER switches to ON and allow a 15 minute warm-up period. 3.4 Zero TI meter if required. 3.5 Connect the 3 M Resistor to TI DC output. 3.6 Set TI output control for VDC and adjust for 900 VDC as monitored on the Digital Multimeter. 3.7 The TI alarm must sound and LEAKAG

9、E lamp must be illuminated. 3.8 Set TI output voltage to minimum. 3.9 Repeat steps 3.5 through 3.8 except set TI and Digital Multimeter to AC and use TI AC output terminals. NOTE If a maximum Leakage current value is required, calculate resistance needed and perform steps 3.5 through 3.8 using the c
