Presets
ThereThere are three preset positions (PRESET A, PRESET B, PRESET C) on the
tester that allows the user to customize the test parameters for their own
equipment. The Preset acts the same way as the normal mode in that it will
only give you a readout of the resistance of the connected system, but
adds a “GOOD” or “BAD” indication based on the system’s preset
parameters:
1. To preset a system, ensure that the system is within
the proper standards for the microphone and/or the proper standards for the microphone and/or
speaker.
2. Plug the system into the tester and move the control
knob to the desired Preset position (either A, B, or C).
3. Confirm the readings for the connected system are
still considered proper readings for a “Good” system.
4. Press the Preset button located at the top of the
system to set that preset to test similar systems as the system to set that preset to test similar systems as the
system connected to the tester.
5. The display will give you an indication that the Preset
has been set and the Microphone and Speaker
readouts will indicate that they are both “GOOD.”
