This combination instrument is also known as a bottom timer. Some show the diver's rate of ascent and descent, which can be is useful for avoiding barotrauma. Digital depth gauges used by divers commonly also include a timer showing the interval of time that the diver has been submerged. Earlier types used a mechanical mechanism and analogue display. Most modern diving depth gauges have an electronic mechanism and digital display. It is a piece of diving equipment used by underwater divers, submarines and submersibles. The relationship between depth and pressure is linear and accurate enough for most practical purposes, and for many purposes, such as diving, it is actually the pressure that is important. They include depth gauges for underwater diving and similar applications, and engineering instruments used to measure the depth of holes and indentations from a reference surface.Ī diving depth gauge is a pressure gauge that displays the equivalent depth below the free surface in water.

The pressure switch should open when oil pressure exceeds appx. Turn on the engine and check resistance.Engine must be turned off for this next step: Connect one lead of the multimeter to the sender terminal and connect the other to a ground on the engine.If the switch remains close at low pressure, meter should show continuity (low resistance).Locate the wire on the switch terminal and disconnect. Use a Volt Meter on this electrical component. To Troubleshoot an Oil Pressure Alarm Switch: Again, if the gauge moves to low-scale, the wiring is grounded, and repair, not, replacement is advised
