The CEM DT-925 is a portable voltage and current calibrator for calibrating process devices and measuring process signals. It sources an adjustable 0-24 mA current and -199.9 to +199.9 mV DC, drives loads up to 500 ohms and measures two-wire current loops with resolution down to 0.01 mA.
The CEM DT-925 is a portable voltage/current calibrator designed for calibrating process devices and measuring process signals in the field. In one compact handheld unit it combines an adjustable calibration source with a mA meter for current loops.
The current source is adjustable from 0 to 24 mA (0.01 mA resolution on the 0-19.99 mA range, 0.1 mA on the 0-24 mA range) and can drive loads up to 500 ohms, while the DC mV source covers -199.9 mV to +199.9 mV with 0.1 mV resolution. In measurement mode the DT-925 reads a two-wire current loop over the same mA ranges.
The instrument carries the CE mark (EMC & LVD) according to EN 61326, EN 61010-1 and EN 61010-02-031, and is rated EN 61010-1 CAT II 600V.
