Measuring Line Voltage
Determine whether the voltage level, voltage waveform, and frequency from an outlet are correct.

Measuring Current
Determine how the current from an outlet is supplied to a load.

Line Voltage and Current Simultaneously Measuring Line Voltage and Current
Determine the influence of the load current on the voltage.

Recording Line Voltage and Current
By recording the voltage and current, you can establish a possible relation between the two.

SAGS & SWELLS. Basically it does the same as the RECORD key, but it can record faster fluctuations. Use the RECORD key for all other combinations of readings you want to record.

Testing Continuity
Check whether a fuse is broken or open by checking continuity. In general, you can check any circuit for open connection.

Measuring Resistance
Measure the resistance of a relay coil (or a resistor).

Measuring Capacitance
Measure the capacitance of a capacitor.

Testing a Diode
Check a diode in both forward direction and reverse direction. Useful for checking whether the diodes in a rectifier are still intact.

Detecting Transients (Phase to Neutral)
Disturbances in a distribution system may cause malfunctioning of many types of devices. For example, resetting computers or false tripping breakers. Events occur occasionally, making it necessary to monitor the system for a period of time to find them. You may look for voltage transients (impulses or spikes) when, for example,
computers are resetting spontaneously.

Monitoring Rapid Voltage Fluctuations
Rapid voltage fluctuations in a distribution system may cause lights to flicker. Deviations of only a few cycles (waveform periods) may result in visible dimming.

SAGS & SWELLS function measures the rms voltage over each cycle and displays deviations.

Measuring Voltage Harmonics
You can perform a quick check on harmonics in a power distribution system by measuring the Total Harmonic Distortion on the voltage.

Measuring Current Harmonics
Non-linear loads produce current harmonics which may cause voltage distortion.

Measuring the Load on a Transformer
Measure the total kVA on all three phases to check the load on a transformer.

Recording the Load on a Transformer
By recording the kVA during several hours, you can find out if there are specific moments during the day that the transformer may become overloaded.

Measuring K-factor
K-factor is an indication of the amount of harmonic currents. High harmonic orders influence the K-factor more than low harmonic orders.

Measuring Current Harmonics
Check whether the lighting system causes excessive harmonics. These may influence the system.

Measuring Power on Single Phase Loads
Inductive loads, such as fluorescent lamps, cause a phase shift between the voltage and the current. This influences the real power consumption.

Measuring Surge Current
Check for a high inrush currents that may cause voltage sags in a ‘weak’ lighting system. A system is considered ‘weak’ when it has a high impedance.

Induction Motors Checking Voltage Imbalance
For 3 phase induction motors, the supply voltage on all three phases should be in balance. Voltage imbalance causes high unbalanced currents in the stator windings, resulting in overheating and reduced motor life.

Checking Current and Current Imbalance
After checking voltage imbalance, check for current and current imbalance. Unbalanced currents cause overheating and reduce motor life. Also single phasing (complete loss of power on one of the phases feeding the motor) may
cause overheating in the two other phase windings.

Measuring Peak and Inrush Current
High inrush currents of motors can cause breakers to trip or fuses to open.

Measuring Power Factor of 3-Phase Motors
A power factor with a value close to 1 means that nearly all supplied power is consumed by the motor. A power factor of less than 1 results in extra currents, called reactive currents. This requires larger power lines and transformers.
Also there will be more power loss in the transmission lines.
Grounded Y-Connection with Balanced Load
For balanced motors with a grounded Y-connection, you can read the Power Factor directly from the screen. To test for a grounded Y, simply check the three phase-to-ground voltages. If the voltages are stable and equal, then the
system is wired as a grounded Y.

Delta connection or floating systems
For delta systems, the procedure is more complex. Use the following procedure to calculate the Power Factor for a 3-phase grounded delta connected motor or for floating sources.

Measuring Voltage Harmonics
When the supply voltage is distorted by harmonics, the motor can suffer from overheating.

Adjustable Speed Drives Checking Current on Phases
When a motor drive is tripping, first check for voltage imbalance (see “Checking Voltage Imbalance”. Then check the current on all three phases feeding the motor.

Measuring Fundamental of Motor Voltage
Check the condition of a drive.

Measuring Frequency of Motor Current
The frequency of the motor current correlates with motor speed.
