Resolution on the lowest range is 1µohm and on the highest range,
100 milli-ohm.
The meter has 6 measuring ranges, from 2000 micro-ohm to 200.0
ohms.
Measurements are displayed on a large 3½ digit custom liquid
crystal display.
This instrument is powered from it's internal rechargeable battery.
It has a regulated DC constant current source with current of 10mA
100mA and 1A.
During recharge of the battery, the instrument is disconnected from
the battery. Measurements can only be made while not charging.
The instrument supply the current to the resistance being measured
through the C
1
and C
2
terminals (C
1
being +, C
2
being -).
The voltage drop across the resistance under test is measured by
the potential terminals P
1
and P
2
(P
1
being +, P
2
being -).
Should the current regulation drops out, the RC Led will lit,
indicating that the resistance in the current circuit is too high.
(Lowering the current by selecting a higher resistance range can
solve the regulation.)
Should the R
P
Led lights up, it mean that the voltage measured on
the resistance is too high, and therefore over-range.
(Lowering the current by selecting a higher resistance range can
solve the over voltage on R
P
.)
The resistance can only be measured precisely when the R
P
and
R
C
Leds do not lit. If anyone of these leds lights up, then the
measurement will be inaccurate.
