- Do not do the verification tests or calibration adjustment in this manual unless qualified
- Xw warning
- To prevent electrical shock personal injury or fire
- The tests that follow verify the functions of the meter if the meter fails the verification tests repair is necessary for meter servicing see how to contact fluke
- Required equipment for the performance tests is in table 2 if the recommended models are not available equipment with equivalent specifications can be used
- Required equipment
- Repairs or meter servicing must be done only by qualified personnel

- Ma dc clamp measure accuracy tests
- Accuracy tests
- Accuracy specifications are valid for 1 year after calibration adjustment when measured at an operation temperature of 18 c to 28 c allow the meter to stabilize at room temperature prior to performing the accuracy tests
- The following tables list the required performance test points for verifying meter accuracy zero the meter prior to completing each measurement point
- Milliamp process clamp meter
- Calibration adjustment
- Volts dc source accuracy tests
- Volts dc measure accuracy tests
- The meter features closed case calibration adjustment with a known reference source the meter measures the applied reference source calculates correction factors and keeps the correction factors in nonvolatile memory
- Ma dc source accuracy tests
- Before you start calibration adjustment let the meter stabilize to room temperature
- To exit calibration mode
- The meter display shows the value in each adjustment step
- The calibration error messages that the meter can show are in table 5 steps to remove the messages are also shown in the table
- Table 4 shows the meter buttons you use to adjust the meters calibration
- Push the calibration button a second time to keep new calibration constants and exit calibration mode
- In source mode the shown value is the meter output
- In measure mode the shown value is the calibrator input
- Calibration error messages
- Volts dc measure adjustment procedure
- To adjust the volt measure function use the calibrator to apply the necessary meter input and do the steps in table 8
- To adjust the ma measure function use the calibrator to apply the necessary meter input and do the steps in table 7
- To adjust the clamp measure function use the calibrator to apply the necessary meter input and do the steps in table 6
- Milliamp process clamp meter
- Ma dc measure adjustment procedure
- Ma dc clamp measure adjustment procedure
- Volts dc source adjust procedure 773 only
- To adjust the volt source function use the calibrator to apply the necessary meter input and do the steps in table 10
- To adjust the ma source function use the calibrator to apply the necessary meter input and do the steps in table 9
- Ma dc source adjust procedure
