5 Quick Start Gui e
5.1 Operation
This section describes typic l, step by step, oper tion of the Micro Junior 2
Open the top protection lid of the c se nd tt ch the test le ds to the test set.
The Two (2) connections on the front pl te m rked +I & -I re the current le ds.
The Two (2) connections on the front pl te m rked +P & -P re the Potenti l or Volt ge le ds.
By connecting test specimen to the Current le ds nd pplying the potenti l le ds ( See figure )
cross the specimen the resist nce re dings will be determined.
Turn the Power switch to the “ON” position.
The Instrument will m ke the initi l
c libr tion check. Then the Initi l R nge
selection screen will ppe r.
Select the current or resist nce r nge
expected to be me sured with the rot ry
knob.
(Selecting the cross current, X10A & X1A me surement r nge.)
Press the rot ry knob when the indic tor is pointing t the resist nce nd current level to be
me sured (If unsure of current level, then st rt t the 1 mA r nge nd incre se the current r nge
until v lid re ding ppe rs).
After the current r nge is selected press the rot ry knob g in. The following me suring modes
