Phase Rotation Testing Tips
1
The measured voltage during phase rotation test
must be >80.0±5VAC. If not, the phase rotation
test can not be performed and “Err” will show on
the top display.
2 After phase rotation test is complete, press SELECT
button to begin a new phase rotation test.
3 Be sure to connect test leads to 3-phase voltage
lines for at least 2 seconds until voltage reading
holds on the bottom display
4 Phase rotation test cannot be performed on Hi-
frequency voltage signals. Be sure voltage lines
are within 50-80Hz to perform the phase rotation
test.
Modular
Expandability
Your SC680 is compatible with Fieldpiece
Accessory Heads. With Fieldpiece Accessory Heads,
you can measure any available parameter, and read
the measurement on your new meter’s display in
real-time, Hold, Max, and min.
Rotate the selector to VDC and stay in mV range.
Remove the probe tips of your test leads, and
connect your accessory head (model AAV3 shown).
