ES5120
3 3/4 DIGIT A/D CONVERTER
When the logic probe function is selected while
FREQ/VOLTSꢀis low (A/D mode). the analog to digital
converter will remain in the autozero mode. The LCD display
will read "OL" and all decimal points will be off. (Fig. 6 -
Display)
If the logic probe is active while FREQ/VOLTS is high
(counter mode) the frequency counter will continue to operate.
The display will read "OL" but the decimal points will be
visible. If the logic probe input is also connected to the
RANGE/FREQ input, then bringing the LOGIC input low will
immediately display the frequency at the logic probe input.
