6.7.2 Measuring pressure with external modules
The calibrator has a digital interface for external pressure modules. These modules
are available for various ranges, including gauge, vacuum, differential and absolute
pressure. The modules work seamlessly in conjunction with the calibrator. Simply
plug them into the interface and select [EXT] (external sensor). Since the interface
between the calibrator and the module is digital, the accuracy and display resolution is
dependent on the pressure module.
6.8 Measuring and sourcing current (4 ... 20 mA)
1. To measure current, use the input terminals on the front of the calibrator. Select the
mA function on the lower display. Current is measured in mA and percentage of the
measuring range. The measuring range on the calibrator is set to 0 % at 4 mA and
100 % at 20 mA.
