Time 7005 Process Loop Calibrator
Includes: Mains battery charger, and user manual.
A precision handheld instrument primarily used for the calibration and simulation of voltage and current loops. The 7005 is a high accuracy loop calibrator incorporating source and measure capabilities. The compact and lightweight design make it easily portable and ideal for plant operations and field use. Combined with user friendly controls and simple operation make this loop calibrator an excellent model for both process engineers and calibration technicians.
In source mode the range can be user programmed to any value between 0 mA and 50 mA, or 0 V and 21 V. For example a low point of 10 mA and a high point of 50 mA could be set giving a span of 40 mA.
Measure mode provides both voltage and current measuring capability with 5 digit resolution. Ranges are 0 to ± 5 V and ± 5 to ± 25 V, 0 to ± 25 mA and ± 25 to ± 125 mA. Alternatively the signal can be measured as a % of span for the following ranges; 4 to 20 mA, 0 to 20 mA, square root 4 to 20 mA, or square root 0 to 20 mA. For all measurements a Min/Max recording function is available on demand.
