Simple to set up, operate, and interpret.
Portable.
Built-in protection against common operator errors.
Operates on 12- or 24-volt power supply.
VEHICLE TEST METER
The VTM tests electrical and mechanical components.
Readings are either pass/fail or digital
displays (PSI, RPM, volts, and so forth).
The VTM interfaces with the vehicle or equipment being tested by either a transducer from the TK
or by a DCA.
Power for the VTM is drawn from the vehicle/equipment batteries or from an alternate power
source.
The flip cards attached to the front of the VTM provide a quick (but limited) reference for the
operator. These flip cards list test numbers, messages, and some procedures. Test limits are
provided for some vehicles.
TRANSDUCER KIT
The transducer kit (TK) is a tray inside the transit case that contains transducers, fittings, and
connectors.
The TK is stored in a molded tray in the top of the transit case. TK item numbers shown in the
illustration are for reference only and do not appear on the tray. Many of the fittings do not have
part number markings on them and are referred to by TK item number and name.
