Philips PM6303M

The Philips PM6303M is a microprocessor-controlled LCR meter engineered for precise measurement of passive component parameters across wide impedance ranges. The instrument combines auto-function and auto-ranging capabilities with a 4-digit LCD display to deliver two measurements per second, making it suitable for laboratory characterization, production QC, field service, and educational environments.

– Technical Specifications

Measurement Parameters
The PM6303M quantifies resistance, capacitance, inductance, quality factor (Q), dissipation factor (D), series and parallel resistance variants (Rs, Rp), impedance (Z), series and parallel capacitance (Cs, Cp), series and parallel inductance (Ls, Lp), and internally biased capacitance (Cs with 2 V BIAS).

Measurement Ranges
• Resistance: 0.001 Ω to 199.99 MΩ
• Capacitance: 0.01 pF to 199.99 mF
• Inductance: 0.01 µH to 199.99 H

Accuracy
• Resistance: ±(0.2% + 2 digits)
• Capacitance: ±(0.5% + 2 digits)
• Inductance: ±(0.5% + 2 digits)

Test Parameters
Test voltage options include 0.3 Vrms, 1 Vrms, and 1 VDC. Frequencies are automatically selected in RCL AUTO mode or user-programmable. The instrument operates across ambient temperatures from +5 °C to +40 °C, with reference accuracy at +23 °C ±1 K.
