3.6 Diode Measurements
1201 uses a current source of 1 mA for diode testing. The maximum
resolution is 10 μV on a fixed range of 1 V DC. The default threshold
voltage is fixed between 0.3 and 0.8 volts and the reading rate is fixed at
0.1 PLC (The voltage bound is adjustable from 0.01V up to 1.2V.). A
“Beep” sound will appear when the diode measured value is in the range.
Warning! Positive end of the source signal is to be cennected to HI
of the input terminals, and the negative end to LO of the input terminals.
How to measure diode
① Selects input signal connections on front or rear panel.
② Connect the diode to the terminals. For forward bias, connect the
probe from input terminal “ HI ” to the positive end of the diode, and
connect the probe from input terminal “LO” to the negative end of the
diode.
③ Set voltage bound via pressing CONFIG + SHIFT + CONT buttons.
When ready, press ENTER. (Or skip this step if you wish to use the
default voltage bound.)
④ Press SHIFT + CONT buttons to select the diode testing function and
observe the reading on the display.
