What are the accuracy specifications for the CSD-723's voltmeter and ammeter across their available ranges?
The CSD-723's voltmeter and ammeter are each specified with 0.2% measurement accuracy across all four switchable ranges: 0–200 mV, 0–2 V, 0–20 V, and 0–200 V for voltage; 0–200 µA, 0–2 mA, 0–20 mA, and 0–200 mA for current. Both meters use a 3.5-digit display, and no accuracy degradation is listed for any specific range, ensuring consistent precision for low- to high-level diode characteristic measurements.
How does the CSD-723's illuminance meter accuracy vary with illuminance level, and under what calibration standard?
The illuminance meter accuracy is calibrated under 2856K white light. Below 10,000 lx the accuracy is ±5% rdg ±10 gdts; above 10,000 lx it degrades to ±10% rdg ±10 gdts. The meter offers four switchable ranges (200 lx, 2000 lx, 20000 lx, 50000 lx) with 0.1 lx resolution, and a sampling rate of 1.5 times/second.
What is the spectral match between the CSD-723's color-sensitive diode and its built-in green light source?
The color-sensitive diode is specified with a green response color and uses a gold-cap color-filter glass lens. The built-in green LED emits at 515–520 nm, which falls within the typical green sensitivity band for such diodes. The complete light source includes six additional discrete wavelengths (red 625–630 nm, orange 600–605 nm, yellow 585–590 nm, blue 460–465 nm, violet 400–405 nm, and white 1000–2500 mcd) for comprehensive spectral characteristic testing.
The Atomfair CSD-723 Color-Sensitive Diode Characteristic Tester integrates a 0.2%-accuracy voltmeter and ammeter with four switchable ranges each, a multi-wavelength LED light source (400–630 nm), and a 0.1 lx resolution illuminance meter, enabling quantitative spectral, volt-ampere, and illumination characteristic studies of green-response color-sensitive diodes in a single benchtop unit.
Positive
- Multi-range electrical measurement: Voltmeter and ammeter each offer four freely switchable ranges (0–200 mV to 0–200 V; 0–200 µA to 0–200 mA) with 0.2% accuracy, supporting precise characterization across a wide operating envelope.
- Broad spectral light source: Integrated LEDs cover violet (400–405 nm) through red (625–630 nm) plus white light, enabling spectral response testing of the green-sensitive diode across the visible spectrum without external optical equipment.
Trade-offs
- Illuminance accuracy depends on calibration: Illuminance meter accuracy is ±5% rdg ±10 gdts below 10,000 lx and ±10% rdg ±10 gdts above, calibrated under 2856K white light; measurements at other color temperatures may deviate.
- Manual range and magnification handling: The 2000 lx range requires ×10 reading magnification and the 50000 lx range ×100, adding manual calculation steps that can introduce operator error during data collection.
