Overview
Digital Multimeter 3-in-1 DM40B with Oscilloscope and Signal Generator, True RMS, 3.5-Inch Touch IPS Display, Orange, for Electronics

The DM40B device combines digital multimeter, oscilloscope, and signal generator in one compact orange casing. The multimeter with a display range of up to 49,999 digits measures both DC and AC voltage, current, resistance, capacitance, frequency, and temperature. It supports True RMS function and automatic range selection. The single-channel oscilloscope with a sampling rate of 50 MSa/s and a bandwidth of 10 MHz displays signal waveforms on a 3.5-inch touch IPS display with a resolution of 480 × 320 px. The built-in generator provides sine, triangle, sawtooth, and square signals for circuit testing.

Main Features:

  • Multimeter with a display range of 49,999, True RMS measurement, automatic range selection for mV/V and µA/mA/A, and simultaneous measurement of AC+DC
  • DC voltage from 500 mV to 1000 V DC with an accuracy of ±(0.03 % + 5 d), AC voltage from 500 mV to 750 V
  • DC and AC current from 500 µA to 10 A through a single common socket A/mA/µA
  • Resistance from 500 Ω to 50 MΩ, capacitance from 5 nF to 50 mF, frequency from 10 Hz to 50 MHz, temperature from -40 to 1000 °C
  • Diode test with four-stage voltage drop evaluation and audible signal, continuity test up to 1 kΩ
  • Relative measurement (REL), MAX/MIN value recording, data hold (HOLD), and trend graph with time base of 160/320/640 ms
  • Oscilloscope with 10-bit ADC, 64 kpts memory, time base from 100 ns to 50 s, sensitivity from 10 mV to 10 V/div, input impedance of 1 MΩ and AC/DC coupling
  • Triggering Auto/Normal/Single, rising/falling edge trigger, adjustable hold-off, and mathematical functions FFT and ABS
  • Generator: sine, triangle, and sawtooth 1 Hz to 50 kHz at 0.5 to 3.0 Vpp; square 1 Hz to 50 kHz with duty cycle 0 to 100 % and 100 kHz to 10 MHz at 3.0 Vpp
  • 3.5-inch touch IPS display with a resolution of 480 × 320 px
  • USB-C interface for screenshot transfer and firmware updates, MCX oscilloscope input, and banana sockets
  • Battery life of approximately 12 hours in multimeter mode and 10 hours in oscilloscope mode, automatic display dimming and shutdown
  • Dimensions 140 × 83 × 25 mm, weight 260 g, operating temperature 0 to 40 °C and humidity up to 75 %
  • Package contents: DM40B multimeter with stand and protective PVC cover, 1 pair of test probes, USB-C cable 1.2 m

The DM40B replaces three separate measuring devices on the workbench while taking up minimal space. Automatic range selection and simultaneous display of AC and DC components simplify measurements without manual adjustment. The 10-bit resolution oscilloscope is suitable for checking PWM signals, power supplies, and transient phenomena in low-frequency circuits. Weighing 260 g, with a stand and protective cover, the device is easy to use on the desk as well as outside the workshop. It is suitable for service technicians, electricians, students, and electronics enthusiasts.
