In fact, the ASME code does not require interlocks or mechanical pressure indicating devices on such doors.

Based on the same principle as the gold-leaf electroscope, repulsion electrometers are more sensitive indicating devices using a form of torsion balance.

Illocutionary force indicating devices (IFIDs)

Searle and Vanderveken (1985) often speak about what they call 'illocutionary force indicating devices' (IFIDs).

Because of this, traditional qinpu do not indicate them (though near the end of the Qing dynasty, a handful of qinpu had started to employ various rhythm indicating devices, such as dots).

In most indicating instruments, the accuracy is guaranteed to a certain percentage of full-scale reading.

Please note that indicating instruments must comply with the requirements of 47 CFR Section 73.1215.

The model base quantities varied by manufacturer and date of design; as amplified indicating instruments became more common, lower base quantities were feasible.

The later machines used as little as 50 volts and 50 mA, used with amplified indicating instruments.

The indicating instruments were of the crudest construction, consisting of two voltmeters connected by "pressure wires" to the centre of electrical distribution.

The trouble was later traced to a faulty wiring harness to the artificial horizon and attitude indicating instruments, which had an intermittent short circuit due to a pinched wire.

Laboratory investigations of the stability of multiple-machine systems were constrained by the use of direct-operated indicating instruments (voltmeters, ammeters, and wattmeters).

A: A station, attended or unattended, must establish suitable monitoring procedures of its equipment and maintainance schedules for the station and indicating instruments to ensure the equipment is operating properly.

This second version was a remote maritime compass device, consisting of ampermeters as the indicating instruments located in different parts of the ship, resistant to magnetic forces or magnetic masses in their vicinity.

The operating frequency was chosen to be high enough to allow high-quality inductors and capacitors to be made, and to be compatible with the available indicating instruments, but not so high that stray capacitance would affect results.
