The K factor is used to calibrate the Frequency Input or to adjust it to match a reference meter. The K factor
operates like a meter factor: The Frequency Input is multiplied by the K factor before additional processing or
calculations are performed.
The default K factor is 1.0. You do not need to change the K factor unless the value of the Frequency Input at
the transmitter does not match the frequency signal from the remote frequency device.
Important
Before changing the K factor:
• Ensure that the wiring between the transmitter and the remote device is intact, and that the remote
device is operating correctly.
• Monitor the frequency signal from the remote device and the Frequency Input value reported by the
transmitter.
— If the discrepancy between the two values is consistent, changing the K factor may be a solution.
— If the discrepancy is erratic, the K factor will not resolve the problem. Verify the wiring, the operation of
the remote device, and the configuration of the remote device. If the problem persists. contact
customer service.
Prerequisites
You must be able to measure the frequency signal from the remote frequency device. If the remote frequency
device is known to be accurate and appropriately calibrated, you can use its data. If you are unsure of its
accuracy or calibration, you can use a digital multimeter (DMM) or similar tool.
Procedure
1. Set the remote frequency device to output a fixed signal.
2. If necessary, measure the signal using a DMM.
3. Read the Frequency Input at the transmitter.
