Clamp meter BM197 2000A AC/DC True RMS, VFD, USB, CAT IV 1000V 102122

Professional Measurement in Challenging Industrial Conditions

Working on installations with high current levels or in environments with significant interference requires equipment that not only measures values but does so precisely and safely. The BM197 clamp meter is designed specifically for such challenges, offering current measurement up to 2000 A and voltage up to 1000 V in safety class CAT IV. Thanks to True RMS technology, the device ensures reliable readings even in circuits with distorted waveforms, which is crucial when working with modern drives or control systems. The large dual LCD display allows simultaneous monitoring of two parameters, while fast sampling (5 times per second) guarantees that no transient change escapes the operator's attention.

Features Facilitating Diagnostics and Safety

In daily service work, time is critical; therefore, this model is equipped with intelligent features that automate the measurement process. The AutoCheck™ mode automatically detects the signal type at the inputs and switches the meter between DC/AC voltage and resistance measurements, eliminating the risk of incorrect configuration before starting work. For installers working with variable frequency drives (VFD), a dedicated low-pass filter (LPF) is available, enabling accurate voltage and frequency readings in the presence of high harmonics—without this filter, results would often be erroneous.

User safety is a priority, confirmed by the high level of overvoltage protection and the capability to perform measurements in the CAT IV 1000V zone. The device also includes voltage detection functions:

• Non-contact detection (NCV/EF): Quick verification of AC voltage presence without touching live parts.
• Contact detection: More precise voltage confirmation using the measurement probe.

Additionally, the meter offers advanced data logging modes:

• CREST-MAX (PEAK HOLD) – records peak values lasting 5 ms, essential for detecting short circuits or current surges.
• MAX/MIN/AVG – automatically tracks maximum, minimum, and average values during the measurement period.
• Relative mode Δ – facilitates comparison of readings against a reference value.

Applications and Expandability

The functionality of this device extends beyond standard electrical measurements. In addition to current and voltage, the BM197 measures resistance up to 40 MΩ, capacitance up to 2000 µF, and temperature over a wide range from -50°C to 1000°C (using a thermocouple probe). Useful features also include continuity tests and diode tests. For documentation and long-term analysis, the meter can be connected to a PC via the optional communication kit KIT BRUA-19X (via USB), enabling data export and report generation directly at the worksite.

Key capabilities of the device include AC/DC current measurements up to 2000 A and voltage up to 1000 V, while maintaining safety class CAT IV. True RMS technology ensures accuracy in nonlinear circuits, and the dual LCD display (6000 + 2000 counts) enables simultaneous monitoring of multiple parameters. The temperature range from -50°C to 1000°C and the ability to measure capacitance up to 2000 µF make it a versatile diagnostic tool. Optional USB communication (KIT BRUA-19X kit) facilitates integration with computer systems.

Thanks to its robust construction and versatile functionality, this clamp meter serves as a complete solution for industrial electricians and power system service technicians who require a single device for most diagnostic tasks.
