NEW FEATURES:

1. The Imrie®630 can measure Positive(+) or Negative(-) voltages without changing the probes around as in previous models. Switching the “POLARITY” switch to the Negative(-) position now means the RED probe will measure Negative(-) voltages.
2. Externally mounted batteries mean no dismantling is required for replacement.
3. Shipped in a “TOOL BOX” type case for storage and handling.
4. Internet downloadable manuals.

PEAK VOLTAGE SCALES:

• 0 – 6 volts.
  • o Measuring Pulse / Trigger coil signals (cranking speeds).
  • o Sensor (TPS, MAP, TIP-OVER, Coolant, Engine and Air temperature, etc) input and output voltages.
  • o Checking for “VOLT-DROP” during engine cranking.
  • o Checking “VOLT-DROP” in Lighting, Battery charging systems etc. etc.

• 0 – 30 volts.
  • o Monitoring Pulse / Trigger coils during engine running tests.
  • o Checking Points Magneto Source coil open circuit output.
  • o Measuring High Speed Exciter coil output (cranking speeds).
  • o Battery charging rate.
  • o Any 6 or 12 volt supplied accessory, sensor or output for correct power supply.

• 0 – 600 volts. (Take care! High voltages can cause serious injury or even death).
  • o Measuring High-Tension coil PRIMARY voltages, cranking and running. Take care with this test!! Check that you are using the correct  “POLARITY”!!!
  • o Checking INJECTOR closing “Back EMF”.
  • o Checking Points Magneto “IN CIRCUIT” primary voltages.
  • o Testing Exciter OPEN and IN CIRCUIT voltages.

• 0 – 30 KV (30,000 volts).
  • o Checking High Tension output, OPEN CIRCUIT.
  • o Checking Spark Plug “FIRING” voltages, at cranking and under all operating conditions.
  • o RESERVE voltage can be calculated from the above tests.
  • o POLARITY switch allows twin lead coil systems to be quickly tested.
