4. Compare the reading on the Meter display with the readings shown in Table 12.
5. If the display reading falls outside of the range shown in Table 12, the Meter does not
meet specification.

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
V
Ω
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 1 - 3 of Table 13.
(Frequency is about 1KHz)
5. Compare the reading on the Meter display with the readings 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:
1. Connect the calibrator to
V
Ω
and
COM
via K-type wire and T-V adaptor
(Ideal 61-465 TC adapter)
Note: The T-V adaptor should be allowed to stabilize to the same room
temperature as the meter before beginning test.
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 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.
