# Agilent E1412A 6.5-Digit High-Accuracy Multimeter, C-Size (Pre-Owned) # Agilent E1412A 6.5-Digit High-Accuracy Multimeter, C-Size (Pre-Owned) ## Key Features At A Glance - 6.5-digit resolution with ±0.0019% DC voltage accuracy for precision measurement applications - C-size, 1-slot, message-based VXI module form factor for system integration - Comprehensive function set: DCV, ACV, DCI, ACI, 2/4-wire resistance, frequency, and period - True RMS AC voltage and current measurements with selectable Slow, Medium, and Fast filters - Up to 1000 readings/second into internal memory at 4.5 digits for high-throughput acquisition - Fast configuration: 65 range changes/second and 30 function changes/second on DCV - Built-in math operations including NULL, MIN/MAX, LIMIT, dB, and dBm - DC voltage range from 100 mV to 300 V with 140 dB DC CMRR for noise rejection The Agilent E1412A is a 6.5-digit high-accuracy multimeter packaged as a C-size, 1-slot, message-based VXI module. It is electrically identical to the E1312A, differing only in mechanical size, and delivers the widest functionality in Agilent's DMM line at price points comparable to 5.5-digit instruments. The module supports a complete set of measurement functions including DC and AC voltage, DC and AC current, 2-wire and 4-wire resistance, frequency, and period. The E1412A serves automated test system applications requiring high measurement throughput combined with precision. Its capabilities include limit checks that drive a TTL output for pass/fail testing, DC voltage ratio measurements, and on-board math operations such as NULL, MIN/MAX, LIMIT, dB, and dBm. Reading storage with internal memory supports buffered acquisition for high-speed test sequences without backplane bottlenecks during capture. ValueTronics International operates from a 20,000 square foot secure warehouse at 1675 Cambridge Drive in Elgin, Illinois, where every unit in our catalog is stored, inspected, and performance-tested by technicians before shipment. We hold inventory we sell rather than drop-ship from third parties, which means the E1412A you order is the unit our team verified against the datasheet specifications above. Buyers acquiring VXI instrumentation for system integration work need predictable lead times and accurate condition reporting, and our in-house testing process is designed to deliver both. ## Brand Heritage Agilent Technologies was spun off from Hewlett-Packard in 1999 as the company's test and measurement business. In 2014, Agilent divided again, with the electronic measurement business becoming Keysight Technologies. Agilent-branded T&M instruments such as the E1412A are part of this lineage, and calibration and service for these instruments now routes through Keysight infrastructure. ## Product Core & Specifications Category Specification Value dc Summary dc voltage 300 V max. dc Summary Voltage accuracy (dc) ± 0.0019% ac Summary ac voltage 300 V max. ac Summary Voltage accuracy (ac) ± 0.07% dc Voltage Measurement method Continuously integrating, multi-slope III A/D converter dc Voltage A/D linearity 0.0002% of reading + 0.0001% of range dc Voltage Input resistance (0.1 V, 1 V, 10 V ranges) Selectable 10 MΩ or 10 GΩ dc Voltage Input resistance (100 V, 300 V ranges) 10 MΩ ± 1% dc Voltage Input bias current <30 pA at 25° C dc Voltage Input terminals Copper alloy dc Voltage Input protection 300 V on all ranges Resistance Measurement method Selectable 4-wire or 2-wire Ω (Current source referenced to low input) Resistance 2/4-wire Ω range 100 MΩ Resistance Max. lead resistance (4-wire Ω) 10% of range per lead for 100 Ω and 1 kΩ per lead on all other ranges Resistance Input protection 300 V on all ranges dc Current Shunt resistor 0.1 Ω for 1 A and 3 A, 5 Ω for 10 mA and 100 mA dc Current Input protection Externally accessible 3 A, 250 V fuse Noise Rejection dc CMMR (60/50 Hz, 1 kΩ unbalance in LO lead) 140 dB Noise Rejection Normal mode rejection (100 PLC / 10 PLC / 1 PLC) 60 dB Noise Rejection Normal mode rejection (<1 PLC) 0 dB System Speed (DC) Function change 30/s System Speed (DC) Range change 65/s System Speed (DC) Autorange time <30 ms System Speed (DC) Max. internal trigger rate 1000/s System Speed (DC) Max. external trigger rate to memory 1000/s ac Voltage Measurement method ac-coupled True RMS — measures the ac component of the input with up to 300 Vdc of bias on any range (Max ac+dc = 300 V rms) ac Voltage Crest factor Maximum 5:1 at full scale ac Voltage ac filter bandwidth (Slow) 3 Hz-300 kHz ac Voltage ac filter bandwidth (Medium) 20 Hz-300 kHz ac Voltage ac filter bandwidth (Fast) 200 Hz-300 kHz ac Voltage Input impedance 1 MΩ ±2%, in parallel with 100 pF ac Voltage Input protection 300 Vrms all ranges ac Current Measurement method Direct couple to the fuse and shunt. ac-coupled True RMS measurement (measures the ac component only) ac Current Shunt resistor 0.1 Ω for 1 A and 3 A ranges ac Current Burden voltage (1A range) <1 Vrms ac Current Burden voltage (3A range) <2 Vrms ac Current Input protection Externally accessible 3 A, 250 V fuse Noise Rejection (AC) ac CMMR (1 kΩ unbalance in LO lead) 70 dB System Speed (AC) Function or range change 5/s System Speed (AC) Autorange time <0.8 s System Speed (AC) ASCII reading to GPIB 50/sec System Speed (AC) Max. internal trigger rate 50/s System Speed (AC) Max. external trigger rate to memory 50/s Frequency/Period Measurement method Reciprocal-counting technique. ac-coupled input using the ac voltage measurement function Frequency/Period Voltage ranges 100 mV rms full scale to 300 V rms.

Input protection on the DC current function uses an externally accessible 3 A, 250 V fuse.**Important:** The E1412A is a VXI module and requires a compatible VXI mainframe for operation; mainframe is not included.**Important:** Errors will occur when attempting to measure the frequency or period of an input following a dc offset voltage change. The input blocking RC time constant must be allowed to fully settle (up to 1 s) before the most accurate measurements are possible.**Important:** Agilent recommends the use of Teflon or other high impedance, low-dielectric absorption wire insulation for dc measurements.**Important:** All frequency counters are susceptible to error when measuring low-voltage, low-frequency signals. Shielding inputs from external noise pickup is critical for minimizing measurement errors. ## About this used unit - Warranty included - Functional verification included - Standard Calibration Upgrade Options: No Calibration Required, NIST Traceable, Z540.1 or ISO 17025 with Data, Z540.3 Guardbanding with Data. - Note that unnecessary accessories may not be included (contact Test Architect to confirm). **Please review the Manufacturer's Data Sheet to verify published specifications.
