DESCRIPTION
The 7065 is a precision indicator module that can be used for pressure or vacuum calibration. It is a simple operation module ideal for
calibrating and cross-checking pressure gauges, sensors, transmitters, transducers, indicators, switches, and many other devices.
The following versions are available; 0.2, vacuum to 2, 5, 10, 20, 35, 70, 100, 200, 400, or 600bar.
Features include a 4.5 digit LCD display, 5 pressure units, zeroing switch and pressure measurement input. Best accuracy is 0.04% of
full scale. For input pressure Time Electronics have a range of pumps including the 7194 benchtop pneumatic pump (vacuum to
120bar) and 7195 hydraulic benchtop pump (vacuum to 600bar). Each pump features a double output manifold to enable connection
to both the module and device under test. They can be used conveniently on the CalBench worktop to provide a precision pressure
source to the 7065 and DUT, with a method that requires minimal user effort.
The 7065 is fitted as standard with an RS-232 interface which is accessible on the rear of the CalBench console or internally connected
to a 7051 calibrator/control centre. This enables communication and read back with EasyCal calibration software (supplied as
standard with the 7051 multifunction calibrator/control centre module). With EasyCal the user can define and perform pressure
calibration procedures as well as create and print traceable calibration certificates.

SPECIFICATIONS

Specifications are for 1 year at 23ºC ±5ºC. Accuracy includes linearity and long term effects.
All accuracies are ±1 digit. For operation outside specified temperature range, apply 70ppm per °C
