5.7 AC and DC Voltage Measurements

CAUTION

Use caution when the measured voltage is greater than 30V DC or AC rms.

Figure 5.2 AC Voltage (left) and DC Voltage (right) Measurement Setups

1. Set the function switch to the AC Voltage or DC Voltage position.
2. Insert the black test lead into the negative (COM) terminal and the red test lead into the positive terminal.
3. Place the probe ends of the test leads in parallel to the part under test.
4. Read the Auto Range voltage measurement on the display.
5. To switch to Manual Range mode, short press the RANGE button. Subsequent short presses of the RANGE button will step through the available ranges. Long press the RANGE button to return to Auto Range mode.
6. Read the frequency (Hz) of an AC signal on the upper secondary display.

5.8 LoZ Voltage Measurements

WARNING

In LoZ mode, the input impedance increases quickly from the initial 2.5kΩ to a few hundred kΩ's on high voltage signals. Peak initial load current, while testing 1000 V AC for example, can be as high as 566 mA (1000 V x 1.414 / 2.5kΩ), decreasing to roughly 3.37 mA (1000 V x 1.414 / 420kΩ) within a fraction of a second. Do not use LoZ mode on circuits that could be damaged by such low input impedance. Use the standard high input impedance voltage modes to minimize loading on such circuits.

CAUTION

Use caution when the measured voltage is greater than 30V DC or AC rms.

LoZ Voltage measurements eliminate the affects of 'ghost' voltages. The procedure for taking LoZ Voltage measurements is essentially the same as for taking standard Voltage measurements, the only difference is that for LoZ Voltage measurements you select the LoZ rotary switch position and you must take into consideration the effect low impedance will have on circuitry that you test (read Warning statement above). Refer to the previous section for other Voltage measurement details.

When you turn the rotary dial to the LoZ position, the display will show 'auto' indicating that the CM94 will automatically detect the measured signal as AC or DC.

5.9 Low Pass Filter (VFD) AC Voltage Measurements

CAUTION

Use caution when the measured voltage is greater than 30V DC or AC rms.

Select the VFD mode using the rotary selector switch.

The VFD feature eliminates high frequency noise in AC voltage measurements by means of a low pass filter. The VFD mode is designed for variable frequency drive measurements. The VFD icon will appear on the display in this mode. The procedure for taking VFD Voltage measurements is identical to the procedure for taking standard Voltage measurements. Refer to the previous sections for Voltage measurement details.

5.10 Current Clamp Measurements

WARNING

Do not measure current on a circuit if the voltage increases to more than 1000 V. This can cause damage to the instrument and can cause injury to persons.

WARNING

Do not use the meter to measure current above the rated frequency. This may cause the magnetic circuits in the jaws to reach hazardous temperatures.

WARNING

Disconnect the test leads from the meter before taking Clamp measurements.

Clamp Measurement Considerations

• Press the jaw trigger to open the jaws and then clamp around the conductor(s) of only one pole of a circuit.
• Ensure that the jaws are completely closed. Enclosing conductor(s) of more than one pole of a circuit may result in differential current measurements.
• Align the conductor(s) to the jaws using the conductor align icons on the clamp jaws.
• Adjacent current-carrying devices such as transformers, motors and conductor wires may affect measurement accuracy.
