• Operating Temperature: -20 °C to 50 °C
• Storage Temperature: -30 °C to 60 °C
• Relative Humidity : ≤ 80% (0 °C ~ 30 °C), ≤75% (30 °C ~ 40 °C), ≤45% (40 °C ~ 50 °C).
• Temperature Coefficient : 0.1 x (specified accuracy) / °C @ (<18 °C or >28 °C) 
• Weight: Approx. 608gm (including battery).

The multimeter has a data logging function that allows users to capture trends and record up to 20,000 data points, enabling thorough analysis. It also includes a time and date function, making it easier to organise data. For added safety, the multimeter alerts users with an alarm and buzzer if incorrect test leads are connected. The instrument measures AC and DC voltage, current, resistance, capacitance, frequency, temperature, and conductance. Special functions include duty cycle, diode and continuity testing, and peak detection. To conserve battery life, it features an auto power-off function that turns off after 15 minutes of inactivity. The device displays maximum, minimum, and relative values and offers a comparison mode for analysis.
