Battery Replacement / Optional Battery When the LOBAT indicator comes on the display, you will need to replace the two 9 Volt batteries. Remove the 4 screws holding the boot on the unit, and remove the boot. Replace both batteries and reattach the boot. To replace the battery, remove the 4 screws holding the protective boot to the front panel. Remove the front panel. On the back of the display board located at the bottom of the board is the primary battery location.
Function Buttons ON OFF Press this button to turn the multimeter on and off. Press this button to set configure the RPM to read in 2 2C/4C Cycle or 4 Cycle mode. Distributorless Ignition Systems should be set to 2 Cycle mode to correctly read RPM. HOLD Press this button to freeze and unfreeze the display. Min Max Pressing the Min/Max button while in certain tests will have set up the meter to capture minimum and maximum readings.
Key Combinations & Special Functions Backlight Control HOLD Min Max Press the HOLD button and the Min/Max button at the same time to turn the backlight on or off. Power up Status Volts V•A Press the Volts and V•A buttons at the same time to disable the auto power off function. Turn the unit off, then back on. The meter will remain on until you turn it off, or the batteries run down.
Volts Pressing the button will cycle you through DC Volts, AC volts, and AC Peak to Peak functions. The bargraph is an easy way to see trends in voltage being measured. Volts The DC volts function is a 10 meg high impedance voltmeter. The AC functions use a certified true RMS chip for accurate measurements of irregular shaped AC waveforms. The Peak to Peak function is the best measurement tool to determine the amplitude of any signal.
Ohms The highest Ohms range allows up to 40M Ohms to be measured. All of the ranges except the lowest use a low current source that will not forward bias semiconductor junctions. The lowest Ohms range does use source current that can cause semiconductor junctions to conduct and affect the readings. Ohms The Diode Volts range will measure semiconductor junction voltages up to 1.999 In the reverse direction an OFL indication is expected.
Amps When the test is first selected the message “PLUG In HI” will be briefly displayed to remind the user that the High range Amps probe should be plugged into the Amps socket. Pressing the button will cycle you through DC Amps, AC Amps, and AC Peak to Peak Amps. The bargraph is a easy way to see trends in amps being measured. Amps The DC Amps function can measure up to +/- 600 Amps. The AC functions use a certified true RMS chip to provide accurate interpretations of AC waveforms.
Lo Amps When the test is first selected the message “PLUG In LO” will be briefly displayed to remind the user that the Low range Amps probe should be plugged into the Amps socket. Pressing the button will cycle you through DC Lo Amps, AC Lo Amps, and AC Peak to Peak Lo Amps. The bargraph is a easy way to see trends in low amps being measured. Lo A The DC Lo Amps function can measure from 10 milliamps to 20 Amps.
Volts • Amps Pressing the button will cycle you through the Volts•Amps Display and a Battery/Starter Test. The High range amp probe is used during this test. The Volts•Amps function displays Amps on the top display, and battery voltage on the bottom display. V•A 238 1 088 LOBAT HOLD MAX MIN AMPS V Volts Amps Display The Battery/Starter Test will display a Crank Engine message (CrnEng).
Time Press the Time button to cycle through Hertz, Pulse Width (Up Slope), Pulse Width (Down Slope), Dwell milliseconds, and Dwell percent tests. The RPM is detected using the Red inductive spark pickup and all time based measurements under this key are made using the voltage test leads. Time The Hertz test measures frequency or cycles/second. The Pulse Width test measures milliseconds when triggered using a positive or a negative slope.
Fuel Test The Black amps probe will need to be connected to the wire that supplies battery power to the fuel pump. Energize the pump to read RPM and Amps, or RPM and AC Peak Amps. When the pump is running, the amperage must read as a positive number or your Fuel Pump RPM will not be correct, or stable.
Coil Test Press this button to cycle through two Current Ramping tests (Peak Amps, Build Time, Drive Time), Ignition KV, and Differential RPM. Coil Build time is the time it takes the current driven into an injector or ignition coil to reach its peak value. Build is the equivalent to Dwell on a current limited ignition. The upper display shows the peak current that the coil was driven to. Drive time is the entire time that the injector is driven open or the ignition coil is driven prior to firing.
Coil Test - KV Test (Requires Optional Adapter) 1. 2. 3. 4. 5. Unplug the Spark Pickup from the multimeter. Connect the KV adapter to the multimeter. Connect the Spark Pickup to the RPM input on the adapter. Connect the ground lead to a good engine ground. The capacitive pickup can be clipped on the spark plug wire being tested, or held against the wire with your hand. 6. Access the KV test on the multimeter by pressing the Coil Button three times.
Coil Test - Fuel Injector Application Peak Amps is the peak current driving the injector. It is regulated by the driver. Typical peak readings are from 1 to 4 amps for a current regulated injector driver, and about 1 amp for a resistance limited injector driver. LOBAT HOLD MAX MIN REL 0 2 38 25 PEAK AMPS mS BLD Build Time, is the time it takes the Peak Amps/Build Display amperage to reach its maximum. Build Time is affected by the solenoid and pintle movement.
Coil Test - Ignition Coil Application Peak Amps is the peak current driving the coil. It is regulated by the module. A typical Peak Amp reading should be about from 5 to 10 amps. Build Time, or ramp time, is the time it takes the amperage to reach its maximum. LOBAT HOLD MAX MIN REL 0 2 38 25 PEAK AMPS mS BLD Peak Amps/Build Display Drive Time is the time the coil is actively driven. Analysis of Test Results If Peak amps is low look for a bad connection between the module and coil.
