Testing the Duty Factor Function
To verify the accuracy of the Meter’s Duty Factor function, do the following:
1. Connect the Calibrator to the VΩ and COM inputs on the Meter.
Note The accuracy of the Calibrator’s Duty function must be appropriate for the specified accuracy of the Meter.
2.Set the rotary switch to Hz.
3.Press the blue button on the meter to toggle to %DF function.
4.Set the Function Generator for square wave voltage for steps
5.Compare the reading on the Meter display with the display reading shown in Table 13.
6.If the display reading falls outside of the range shown in Table 13, the Meter does not meet specification.

Testing the Temperature Function
To verify the accuracy of the Meter’s Temperature Function do the following:
1Connect the calibrator to VΩ and via

2. Set the rotary switch to °C.
3 Set the Calibrator for inputs in Table 14.
4.Compare the reading on the Meter display with the display reading shown in Table 14.
5.If the display reading falls outside of the range shown in Table 14, the Meter does not meet specification.
