7. FUNCTIONS
7-1 TRAC-LOK MODE (Model 3007A)
TRAC mode : Measurement can be conducted while the test button is
being pressed.
When making continuous measurement, select this mode.
LOK mode : When the test button is pressed, measurement can be conducted
only once, and output is stopped, then automatically discharged.
This allows to economize on the battery life.
7-2 AUTO NULL
When conducting continuity tests, the contact resistance of test probes etc.
is automatically subtracted before the real resistance is displayed to obtain
more accurate reading.
This function is invalid when the contact resistance, etc. is 10 Ω or more.
・ NULL symbol ( ) is displayed while AUTO NULL function is working.
・ AUTO NULL will be cancelled when the instrument is powered off.
7-3 BACK LIGHT (Model 3007A)
Use BACK LIGHT to facilitate working at night or dimly lit situations.
When the back light switch is pressed with the function switch in any
position except "OFF", the back light continues illuminating for approx. 40
seconds and then turns off automatically.
When the back light switch is pressed again, the BACK LIGHT will turn off
even within the lighting time.
Press the back light switch while it is on, the light gets brighter. Press it
again to turn it OFF.

The instrument automatically turns off approx. 10 minutes after the last
switch operation. To return to the normal mode, turn the function switch
