The Agilent 3458A Auto-Calibration (ACAL) function removes measurement errors caused by component temperature and time drift. For maximum accuracy, ACAL should be performed every 24 hours. For example, addi- tional Vdc volts gain errors due to temperature changes are reduced from 1 ppm/ C to 0.15 ppm/ C (over 6:1) using ACAL. Re: HP 3458A 8.5 digit calibration questions. « Reply #4 on: July 08, 2016, 06:52:58 am ». Of course there is a command for storing a calibration string. RTFM, please use calibration manual, page 74, or user manual, page 165: CALSTR string [,security_code] stores the string in non-volatile memory, maybe secured by the calibration security 8508A and 3458A emulation mode Fully support MET/CAL™ calibration procedures library in Fluke 8508A emulation IVI driver USB thumb drive for convenient data transfer in .csv format Trigger mechanisms Manual trigger External BNC Trig In and Trig Out Internal or level trigger Timer trigger Epoch trigger Line trigger BUS trigger CE and CSA compliant The 3458A introduces new heights of true rms AC volts performance with a choice of traditional analog or a new sampling technique for higher accuracy. For calibration sources and periodic waveforms from 1 Hz to 10 MHz, the 3458A's precision sampling technique offers extraordinary accuracy. With 100 ppm This manual has information to perform assembly level troubleshooting of the 3458A Multimeter. Included are the removal/installation procedures of the instrument's printed circuit board assemblies, and a parts list. This manual is intended for use by service-trained personnel only. HP 3458A/HFL Special Laboratory Digital Multimeter 6 An excerpt from a Microsoft Visual Basic program that programs all of the Fluke HP 3458A/HFL key configurations is shown below. The program was written using Microsoft Visual Basic 5.0 for the National Instruments AT-GPIB/TNT (Plug and Play) IEEE card.

The 8558A 8.5 digit multimeter offers 5 mega-samples-per-second high resolution digitizing for system automation in labs and manufacturing test environments. Fluke's new high-speed system design and the industry's fastest direct digitizing capability enable significant throughput increases for many automated system applications that require One of spectacular instruments which survived thru decades and three brands is metrology-grade 8½-digit Model 3458A multimeter, with its famous ultra-linear ADC. This meter is still selling and supported on market, with brand new cost reaching over $9500 USD, in base configuration. It was introduced back in 1989 with MSRP $6000 USD. 3458A Multimeter Calibration Manual, Edition 6 3458A Multimeter Assembly Level Repair Manual, Edition 2 3458A Multimeter Component Level Repair Manual Service notes There are service notes/engineering changes were published during years of 3458A's lifecycle. If your unit is old, worth to check if any of them required to do. The Agilent 3458A Auto-Calibration (ACAL) function removes measurement errors caused by component temperature and time drift.
