• True RMS measurement
• 9999 counts
• Auto/manual ranging
• Display backlight
• Auto power off

The Instek GDM-532 is a 9999-count true RMS digital multimeter with high resolution, auto range and a new intelligent ADC chip. Designed according to CAT II 1000V/CAT III 600V, the meter comes with overvoltage and overcurrent alarms, and a false detection protector for 6kV electric shock and high voltages.

Features include:

• 9999-count display, true RMS measurement, and fast ADC (3 times/s)
• Full-featured false detection protection for up to 1000V surge, and overvoltage/overcurrent alarm
• Extended measuring range, especially for capacitance (compared with similar products), the ≤9.999mF response time within 6s
• Optimized NCV function: EFHi mode to distinguish neutral and live wires, EFLo mode for low electric fields, and audio/visual alarm
• Recoverable and anti-burning protector is built into the current input terminal
• Measurement of flame sensor of heating device can be performed at µA position.
• Current (AC/DC) mode memory function.
• Low power consumption (general: 2mA; sleep state: <30µA) to effectively extend the battery life to 500 hours

There are several models in the GDM-500 series. Please click here for an overview of meters in the series and a breakdown of the main features and differences in each.
