It measures DC resistance (R), DC current (I), surface resistivity (ps), and volume resistivity (pv), with a measurement range from 1 × 10³ Ω to 1.6 × 10¹⁶ Ω and a basic accuracy of 0.6%. High-resistance measurement is used to characterize insulation integrity, dielectric properties, and leakage behavior in passive components and materials. The HP 4339A is designed for measurement of capacitors, relays, switches, connectors, materials, cables, and PC boards. The grounded device-under-test capability supports measurement of cables and transformers under grounded conditions, which is required for evaluating components in their installed reference configuration. ValueTronics stocks, tests, and ships precision component-measurement instruments like the HP 4339A from our 20,000 sq ft secure warehouse at 1675 Cambridge Drive in Elgin, Illinois. Every pre-owned unit is inspected and functionally verified by our in-house technical team before it leaves the building, so the instrument arriving on your bench performs as the documentation describes — not as a distant listing photo suggests. ## Brand Heritage Hewlett-Packard's test and measurement business was spun out as Agilent Technologies in 1999 and then transferred to Keysight Technologies in 2014. Instruments originally branded HP, like the 4339A, are part of the lineage that today carries the Keysight name. ## Accessories Supplied - Operation manual - Shunt connector - Power cable ## Product Core & Specifications Specification Value Measurement Parameters R (dc resistance), I (dc current), ps (surface resistivity), pv (volume resistivity) Measurement Range (I) 60 fA to 100 µA Measurement Range (R) 1 x 10^3 Ω to 1.6 x 10^16 Ω Basic Accuracy (I) ±0.4% Basic Accuracy (R) ±0.6% Measurement Time (Short) 10 ms (typical) Measurement Time (Medium) 30 ms (typical) Measurement Time (Long) 390 ms (typical) Display 5 digits (max) Mathematical Functions Deviation and percent deviation Ranging Auto and manual Trigger Internal, external, manual, and HP-IB Delay Time 0 to 9999 ms in 1 ms steps Test Cable Lengths 2 m maximum Averaging 1 to 256 Test Voltage 0.1 to 1000 Vdc, 0.1 V steps @ 0.1 to 200 V, 1 V steps @ 200 to 1000 V Voltage Accuracy (0.16% + 100 mV) @ ≤ 200 V; (0.16% + 500 mV) @ > 200 V Maximum Current 10 mA @ ≤ 100 V, 5 mA @ ≤ 250 V, 2 mA @ ≤ 500 V, 1 mA @ ≤ 1 kV Current Compliance Setting 0.5 mA, 1 mA, 2 mA, 5 mA, 10 mA Output Resistance 1 kΩ ±10% Input Resistance 1 kΩ ±10% Correction Function Zero OPEN: Eliminates measurement errors due to stray parasitic resistance in the test fixtures Test Sequence Program Controls a series of resistance measurements.
