Extreme Static Discharge
In the event that the analyzer is exposed to an extreme static discharge, readings may appear to freeze. Although the until will not be damaged by static, you may need to press any function key to restart measurements.

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. This position must be filled with a full sized 9 volt battery. A second position towards the top of the analog board will hold a second 9 volt battery. This is an auxiliary battery that is not required for use. However, for extended battery life when connected to a PC, or extended use of the backlight a second battery is recommended.

Function Buttons
Press this button to turn the multimeter on and off.
Press this button to set configure the RPM to read in 2 Cycle or 4 Cycle mode. Distributorless Ignition Systems should be set to 2 Cycle mode to correctly read RPM.
Press this button to freeze and unfreeze the display.
Pressing the Min/Max button while in certain tests
will have set up the meter to capture minimum and maximum readings. Continue to press this button to view the min and max readings on the top display. Press
any other test button to stop capturing minimums and maximums.
Press the Range button to manually set the range of most tests. Press any other test button to return to auto ranging.
Press the REL Zero button to zero out the reading on the bottom display. Use this button to zero the low and high amps probe, or zero out the ohm meter. This function can also be used to set a base measurement as zero. Then all readings will be +/- from the base reading.

Key Combinations & Special Functions
Backlight Control
Press the HOLD button and the Min/Max button at the same time to turn the backlight
on or off.
Power up Status
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.
Software Version
Press the V•A, Time, Fuel and Coil buttons at the same time to display the software version of the multimeter.

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.
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.
Note: AC auto ranging takes more time to occur than DC auto ranging. This is to allow the AC peak and rms circuits to settle after the abrupt change in scaling.

Continuity Display
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.
The Diode Volts range will measure semiconductor junction voltages up to
1.999 In the reverse direction an OFL indication is expected.
The continuity test, indicated by both the beeper symbol and the Ohms symbol being active, uses the lowest Ohms range. Anytime the reading goes below 100 the beeper will sound.
Note: The meter is equipped with a self protection device that will protect the ohms function in case the test leads are connected to battery voltage.
