7005 Process Loop Calibrator

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.

The three operating modes provide a fast and easy solution to process applications; Loop current/voltage source for simulating a transmitter and the loop supply, sink of loop current for simulating a transmitter, and measurement of loop current/voltage for simulating a loop indicator.

An internal NiMH battery powers the unit for typically 9 hours continuous use and an external mains charger is supplied as standard. An automatic power-down feature is incorporated to conserve battery life, which can be disabled if not required. The 7005 is constructed in an impact resistant ABS case and connections are made via 4 mm binding terminals on the top of the unit.

7005 Operating Modes

Source and Measure Modes

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.

7005 Stepping and Ramping

Stepping and Ramping

Manual step of the output is possible at five calibration points; 0%, 25%, 50%, 75% and 100% of span. Automatic stepping of the output is also available, both up and down with programmable dwell times.

Continuous up/down ramping can also be performed, with user programmable ramp rates and dwell time (top and bottom).
