Where the GPS-135A excels
Incoming inspection
Fast pass/fail sorting of inductors, capacitors and resistors using comparator bins and auto‑range.
R&D bench work
Primary L/C/R/Z with secondary Q, D, ESR and θ — characterize components across 100 Hz to 100 kHz.
Production QA
Stable 100 Ω source and 0.6 Vrms drive improve repeatability; USB/SCPI for logging and traceability.
Service & troubleshooting
Quick ESR and dissipation checks on electrolytics; open/short/load correction minimizes fixture errors.
On‑site verification
Handheld form factor with long runtime; dual display and HOLD for easy reading in the field.
Education & labs
Clear dual display shows main & secondary parameters — great for teaching impedance concepts.
