The wide band precision high voltage divider of series HST expand the voltage measuring range of ZES ZIMMER precision power meter LMG for use at nominal voltages over 1000V. The high voltage inputs are equipped with 2m leads that are attached to the voltage measured against earth. The open leads can be finished by the customer. The HST3 (resp. HST6/9/12) divides DC, AC or any distorted voltages with very high accuracy by the factor 1000 (resp. 2000/3000/4000). The divided voltage is available at the buffered low impedance BNC output. To avoid noise interference it is recommended to use shielded cables to the measuring input of the LMG. The HST can be delivered as one-, two- or three-channel version to match the particular measuring task.
Not for measurements directly on the grid!
