  • Page 28: Measurement Configuration

    Measurement Configuration Most measurement parameters are user-defined. Changing a measurement parameter will change the measurement precision and speed as well as the input impedance. An appropriate measurement parameter based on the actual application will ensure faster measurement or higher measurement precision. The default measurement configurations of the multimeter can ensure the accuracy of the measurement results in most cases.

  • Page 29: Range

    Range This multimeter provides auto and manual range selecting modes. In auto mode, the multimeter selects a proper range automatically according to the input signal; in manual mode, you can use the front panel key or menu key to set the range. The auto mode can bring a lot of convenience for users while the manual mode provides higher reading precision.
  • Page 30 Note: 1. “overload” will be displayed when the input signal exceeds the current range. 2. By default, the range is set to Auto at power-on or after a reset. 3. Auto mode is recommended if you are not sure about the measurement range in order to protect the instrument and obtain accurate data.

  • Page 31: Intergration Time And Resolution

    Intergration Time and Resolution Integration time is the period during which the multimeter’s analog-to-digital (A/D) converter samples the input signal for a measurement. The longer the integration time is, the slower the measurement speed will be and the higher the resolution will be; the shorter the integration time is, the faster the measurement will be and the lower the resolution will be.
  • Page 32 Table 2-2 Relationship between reading resolution and integration time Resolution Intergration time 0.005 PLC / 0.006PLC 4½ 0.05 PLC / 0.06PLC 0.5 PLC / 0.6PLC 5½ 1 PLC 6½ 10 PLC 100 C 2. In ACV, ACI ,FREQ/PERIOD measurements, the resolution is fixed at 6½ digits.

  • Page 33: Dc Impedance

    DC Impedance DC impedance applies to DCV measurement. The default is “10MΩ”. In the range of 200 mV, 2 V or 20 V, you can choose “>10GΩ” to reduce the loading error to the measured object caused by the multimeter In the range of 200 mV, 2 V or 20 V under DCV measurement, press 【Input Z】...

  • Page 34: Auto Zero

    Auto Zero Auto zero (Auto Zero) applies to DCV, DCI, 2WR and 4WR measurements. Enter the specific measurement function and press【Auto Zero】in the menu to perform the setting, as shown in Diagram 2-5 (take DCV measurement for instance). Diagram 2-5 Turn on or off Auto Zero ON: the multimeter internally disconnects the input signal and measured circuit after each measurement, and takes a zero reading.

  • Page 35: Ac Filter

    AC Filter AC filter applies to ACV and ACI measurements. It can optimize the low-frequency accuracy and minimize the AC settling time. This multimeter provides three types of AC filters (>3Hz, >20Hz, >200Hz). The AC filter to be used is determined by the input signal frequency. You should generally select the highest frequency filter whose frequency is less than that of the signal you are measuring, because higher frequency filters result in faster measurements.

  • Page 36: Short-Circuit Resistance

    Short-circuit Resistance This function only applies to continuity test. When the measured circuit has a resistance lower than the short-circuit resistance, the circuit is considered as connected, and the beeper sounds (if sound is on). The default short-circuit resistance is 50 Ω and the setting is stored in nonvolatile memory. When continuity test is enabled, Set the 【Threshold】(equal to short-circuit resistance) using the direction keys.

  • Page 37: Gate Time

    Gate Time Gate time (also called Aperture Time) applies to FREQ/PERIOD function. It decides the resolution of low-frequency measurement. The longer the gate time is, the higher the resolution of the low-frequency measurement is and the slower the measurement is, and vice versa. In FREQ/PERIOD measurement, press 【Gate Time】to show the setting options, as shown in Diagram 2-8 (take FREQ measurement for instance).

    Hold Measurement Function Hold Measurement function provides users with a stable reading on the screen of the front panel. When the test leads are put away, the reading is still held on the screen, which makes users can view measured history data. Press to open Hold measurement function interface, the black field just above the screen will show “·Probe Hold”, as shown in the...

    Chapter 3 Measurement Tutorial True RMS AC Measurement The AC measurement of the Multimeter has true RMS response. The power dissipated in a resistor within a time is proportional to the square of the measured true RMS voltage, independent of wave shape. The instrument can accurately measure true RMS voltage or current, as long as the wave shape contains negligible energy above the effective bandwidth.

    Crest Factor Errors (non-sinusoidal inputs) A common misconception is that "since an ac Multimeter is true RMS, its sine wave accuracy specifications apply to all waveforms." Actually, the shape of the input signal can dramatically affect measurement accuracy. A common way to describe signal wave shapes is “crest factor”.
