Description

The CEM DT-9928 professional digital multimeters is a comprehensive collection of high – performance measuring tools designed to meet the diverse needs of professionals in electrical, electronic, and industrial fields.

Key Features

1. High – Resolution Digital Displays

These multimeters come with different digital display counts, offering enhanced precision. The DT – 9926, DT – 9927, and DT – 9927T models feature 6000 – count displays, the DT – 9928 and DT – 9928T models have 11,000 – count displays, and the DT – 9938 model boasts a 22,000 – count display. With maximum resolutions reaching up to 0.01mV/0.01µA/0.01Ω in some models, they can provide highly accurate readings for a wide range of electrical measurements.

2. True RMS Measurement (Select Models)

The DT – 9927T and DT – 9928T models are equipped with True RMS technology. This allows them to accurately measure the root mean square value of AC voltage and current, even for non – sinusoidal waveforms. In industrial and electrical environments where power supply waveforms can be distorted, True RMS measurement ensures reliable and precise results.

3. Analog Bargraph/Segment Display (Certain Models)

The DT – 9926, DT – 9927, and DT – 9927T models feature an analog bargraph/segment display with 61 segments. This visual aid provides a quick indication of the measured value’s magnitude and trends, complementing the digital readout for more intuitive data interpretation.

4. Safety – First Design

Safety is a top priority for these multimeters. They comply with EN61010 – 1 safety standards, meeting CAT IV 600V and CAT III 1000V requirements. All ranges are protected against 1000V inputs, and the current ranges have 10A/1000V and 0.5A/1000V fuses for added protection. This ensures user safety during operation, even in high – voltage and high – current environments.

5. Multiple Measurement Modes

Relative Mode: All models support a relative mode, which allows users to set a reference value and measure deviations from it. This is useful for applications such as comparing component values or measuring changes in electrical parameters.
Data Hold: The data hold function freezes the display reading, making it convenient to record measurements without the need to worry about the value changing.
MAX/MIN Recording Mode: All models can record the maximum and minimum values during a measurement session. This is beneficial for monitoring fluctuations in electrical signals over time, helping to identify peak values and trends.

6. Auto – Ranging and Auto Power – Off

The auto – ranging feature automatically selects the appropriate measurement range, eliminating the need for manual range selection and reducing the risk of measurement errors. Additionally, the auto power – off function conserves battery life by turning off the multimeter after a period of inactivity.

7. Wide Measurement Capabilities

Electrical Measurements: They can measure DC and AC voltage up to 1000V, DC and AC current up to 10A, and resistance up to 40MΩ with high accuracy. The basic accuracy for these measurements ranges from ±0.09% for DC voltage to ±1.5% for AC current.
Other Functions: The multimeters also support measurements of duty cycle (up to 99.90% with ±1.2% accuracy), frequency (up to 10MHz with ±0.1% accuracy), and capacitance (up to 40mF with ±3.5% accuracy). Some models can measure temperatures up to 760ºC/1400ºF with a Type K temperature probe, with an accuracy of ±3.0%. Moreover, all models are capable of diode checks and continuity tests.

8. Wide Capacitance Ranges (Differentiated by Model)

The DT – 9926, DT – 9927, and DT – 9927T models can measure capacitance up to 1000µF, while the DT – 9928 and DT – 9928T models have an extended range of up to 110mF, providing flexibility for different capacitance measurement requirements.
