Is the 0.2% measurement accuracy of the built-in voltmeter and ammeter specified as a percentage of reading or of full scale?
The product description specifies a measurement accuracy of 0.2% for both the voltmeter (4 ranges: 0-200mV to 0-200V) and ammeter (4 ranges: 0-200μA to 0-200mA), but does not clarify whether this is percentage of reading or full scale. For precise low-level measurements, users should contact inquiry@atomfair.com to confirm the specification. The 3.5-digit display mode applies to all ranges.
What are the accuracy and calibration conditions for the built-in illuminance meter at high illumination levels (above 10,000 lx)?
The illuminance meter has an accuracy of ±10% of reading ±10 digits for measurements above 10,000 lx (on the 20000 lx and 50000 lx ranges). For ≤10,000 lx, accuracy is ±5% rdg ±10 gdts. Calibration is performed under 2856K white light. The 50000 lx range uses a ×100 reading rule, and the 2000 lx range uses ×10.
What are the permitted voltage and environmental tolerances for reliable operation of the Atomfair-PDE-638?
The instrument requires AC220V ±15% (187V–253V) at 50Hz ±5% and an operating temperature of 0°C–40°C with humidity ≤80%. These conditions ensure stable performance of the light source, voltmeter, ammeter, and illuminance meter. Exceeding these tolerances may degrade measurement accuracy or cause damage.
The Atomfair-PDE-638 integrates a 0.2% accuracy voltmeter/ammeter with a 7-wavelength LED source and a 0.1 lx resolution illuminance meter, enabling multi-parameter characterization of photodetectors including dark current, spectral response, and time response in a single benchtop unit.
Positive
- Multi-wavelength spectral testing: Seven switchable wavelength bands from 400 nm to 630 nm plus white light enable spectral characteristic measurements across the visible spectrum, supporting photoresistor, photodiode, and solar cell characterization without external light sources.
- Integrated precision measurement: Built-in voltmeter and ammeter with 0.2% accuracy and four auto-switchable ranges each (voltage up to 200 V, current up to 200 mA) allow direct dark current, photocurrent, and volt-ampere curve acquisition without additional instruments.
Trade-offs
- Mains power dependency: Requires AC220V ±15%, 50Hz ±5% supply, limiting portability and necessitating stable laboratory power infrastructure; operation outside this range may affect measurement accuracy.
- Environmental sensitivity: Specified for 0-40°C and ≤80% humidity, so high-humidity or temperature-extreme labs may need environmental controls to maintain the stated 0.2% measurement accuracy and illuminance linearity.
