The MS8050 True RMS Multimeter is a digital multimeter designed and manufactured in accordance with international electrical safety standards. The meter has multiple measurement functions, including AC voltage, DC voltage, DC millivolt, AC millivolt, logic frequency, duty cycle, diode, resistance, continuity, capacitance, DC microampere, AC microampere, DC milliampere, AC milliampere, DC ampere, AC ampere, linear frequency, relative value, maximum value, minimum value, data hold, data storage and playback, etc. The meter complies with international electrical safety standards and is certified by the European Union.
This manual begins with safety information, warning users to inspect the instrument for damage, ensure proper grounding, and avoid use in flammable or wet environments. It also outlines the required protective measures when measuring high voltages up to 1000 V RMS.
The guide describes the front‑panel layout, connector functions (COM, A, mA/µA, etc.), measurement modes (voltage, current, resistance, capacitance, frequency, dBm), data‑storage features such as HOLD and RS‑232C communication, and maintenance procedures including fuse replacement and calibration. This manual is written in Chinese.
| Maximum Input Voltage | 1000 V RMS |
|---|---|
| Measurement Accuracy (Voltage) | ±0.03 % |
| Capacitance Measurement Range | 0.01 nF – 300 µF |
| Current Measurement Range | 0.5 A – 10 A |

Remove the old fuse and install a new fuse of the same type and rating (e.g., 0.54 A/230 V or 0.63 A/500 V) as specified on the back panel.
Calibration should be performed by qualified personnel using a high‑precision reference signal source; the manual provides detailed steps for internal calibration.
