  • Page 2: Input Connector

    The lower part of the HT101S is the diagnostic and sensor simulator center. When used with the “In-Line” Tester TEE Harness the HT101S will monitor the Voltages supplied to the sensor, from the display, and additionally allow the signals generated by the sensor to be checked for presence and accuracy. When dialed to Digital or Analog Simulate, the HT101S sends simulated signals to the display allowing all the connecting cables to be checked while verifying the Controlling Display correctly reads the signals being sent.

    5 volts to the antenna to operate an internal amplifier. Disconnect the cable from the gps antenna and re-install at COAX on the HT101S. When VOLTS is selected you should see 5 to 12 volts on the meter indicating a good connection from the antenna connection to the gps receiver.
  • Page 4 When the Stand-Alone harness is used, DIGITAL SIMULATE is used to check the sensor, independent from the display. The HT101S provides the Supply Voltage and the Signal Generated is available for tests at the YELLOW test jack. You’ll see the Yellow LED blink as the pulses are generated and the Frequency can be read by connecting the Meter to the Yellow and Black test jacks.
  • Page 5 TYPES OF SENSORS TO BE TESTED The HT101S is designed to be compatible with any sensor on any machine. In some cases special cabling is needed. These sensors require in some cases, very specific operating voltages. Sensors generally fall into two groups; DIGITAL and ANALOG.
  • Page 6 Flow Sensors Flow Meters can be bench using the HT101S set up as done for the Shaft Speed Sensors. Set the Function Switch to Digital Simulate. Set the Meter Function to Frequency and the Connected Point to Patch.

  • Page 7: In-Line Testing

    Zero to 100 pound sensors can be tested on the bench using air pressure regulated to provide the test pressures. Hydraulic pressure sensors need typically 3,000 pounds of pressure which can be a challenge providing on the bench. Using the HT101S In-Line Testing Use Tester TEE In-Line Harness TT-AE27994...
