Dear Forum,
I am currently looking for a Bench-DMM, that fits my needs. One of the main applications, apart from general bench use, will be testing DCDC and ACDC converters. Accuracy-wise 4.5 digits will be more than sufficient. Simultaneous display of DC-Current and DC-Voltage (often called dual-display) for eff. estimation would be a HUGE bonus. Since I am also aiming at automation, GPIB and/or LXI are welcome, a serial interface would be mandatory.
Now setting the budget to around 400 euros, I am facing the following options:
* A used 34401A, qood quality meter, no dual display, only 3A Current range, GPIB-interface
* A used FLUKE 45, 10A current range, GPIB per option available, very old
* A new Siglent 3045X, dual display and current range up to 10A and LXI-interface
* A new GW-Instek GDM-8341 4.5 digit meter with dual-display and usb-serial-interface
Dismissing the FLUKE (400 is imo very expensive for the age of the instrument) and the GW-Instek (I'd prefer a proper GPIB or LXI Interface over the usb-serial stuff). I am torn between the 34401A and the Siglent. Normally I'd rather aim for high quality, but used, than for cheap new equipment but the dual-display option and the high current range seem very appealing to me for general bench use (without automation involved).
What would you do? Any siglent users? Thank you very much for your input!
