Setting the measured frequency

When the display value

is wrong

1. When the voltage or current display value is lower than

expected

The voltage value is low:

• Is the voltage clip connected to the power line being tested?

• Is the voltage cord inserted in the voltage connector?

The current value is low:

• Is the clamp-on sensor inserted in the device’s current connector?

2. When the active power display value is negative

• Is the voltage cord of the channel displaying the negative value con-

nected properly?

• Is the arrow (printed on the clamp) on the clamp-on sensor for the

channel displaying the negative value pointing to the loaded side?

3. When the voltage display value differs from the expected

value of three-phase connections

• Are the phase-to-neutral voltage and line-to-line voltage (voltage cal-

culation methods) selections different?
