The Brookfield DV-I+ Viscosimeter Operation Manual provides setup, operation, spindle selection, and maintenance instructions.
This manual describes the Brookfield DV-I+ viscosimeter, a laboratory instrument for measuring liquid viscosity. It covers the principle of viscosity measurement, the instrument’s components, and how to install and configure the device, including power requirements and optional temperature probe.
Detailed operating procedures are provided for automatic zeroing, selecting spindles and speeds, using auto‑range, choosing measurement units, and advanced functions such as Timed Stop and Time‑to‑Torque. Calibration methods, standard liquids, and safety notes are also included.
