Noise Countermeasures 11.4 Noise Countermeasures This section describes how to deal with a noisy environment. Noise contamination mechanisms Noise sources Manufacturing plants use large currents at 50 Hz/60 Hz as a source of power. Many loads are characterized by an inductive load, for example motors and solenoids. Equipment such as inverters and high-frequency induction furnaces uses capacitor input-type switching power supplies that carry large pulsed currents.

Noise Countermeasures Example noise countermeasures Ensuring devices are grounded reliably • Ground the instrument and wireless modules reliably. You can ground the chassis by connecting the AC Adapter’s grounded two-prong power cord to an outlet with a grounding electrode. • Ensure the measurement target’s chassis is grounded reliably. Ensure the measurement target’s chassis is reliably connected to a suitable ground.

Keep signal lines (thermocouples) away from wires that could serve as sources of noise (power supply lines, etc.).
Page 284 Noise Countermeasures Adding capacitors to signal lines An effective way to address noise caused by superposed signal sources or high-frequency pulses is to insert a capacitor between the positive and negative input terminals. The capacitor will keep the noise out of the device’s internal circuitry. Use a capacitor whose rated voltage is greater than the voltage being input.

Configure the settings as follows in the [Input] area for the channel being measured: Input type Voltage Range 1-5 V Ω Since a 250 resistor has been connected to the input terminals, 4 mA will be recorded as 1 V, and 20 mA will be recorded as 5 V.
Page 299: Measuring Power Consumption Using Pulse Output From A Watt-Hour Meter
Application Measurement Measuring power consumption using pulse output from a watt-hour meter This section introduces a method for measuring pulses from a watt-hour meter and converting them to power consumption. The method involves measuring the pulse output from a watt-hour meter (50,000 pulses per kWh) and recording the power consumption every 30 min.
