ESI-870 Resistance/Resistivity Indicator

5.
Connect a fresh battery to the instrument battery power connector and
insert the new battery into the case. Take care to position the battery
connector wires to allow the battery cover to close easily.
6.
Replace the battery cover on the back of the meter by positioning it in the
guide grooves and sliding it forward carefully. Use the thumb of one hand
to maintain downward pressure on the cover and to keep it aligned. At the
same time, use the thumb of your other hand to apply pressure to the end
of the battery cover and slide it into its locked position.
a.
Do not over force the cover closed. It should snap into its locked
position with firm, yet relatively gentle pressure.
b.
If the cover does not easily lock closed, remove the cover and
battery. Reinsert it to obtain a better fit. Be sure connector wires
are positioned not to obstruct the battery compartment cover.
7.
The ESI-870 is now ready for testing and use.
B.
Initial Operational Check
Once the battery is installed in the ESI-870, check its initial function as follows.
Note that this procedure should be conducted each time the instrument is used,
and whenever the instrument's performance or battery function are in question.
1.
Place the instrument, with electrodes down, on a clean metal surface such
as the PTB-915 Test Bed. Measure the resistance of the plate using the
"ESI-870 Operation Procedures" described below, i.e., Push the "Press to
Test" button and observe LED indication.
a.
The Yellow LED located at
left end of the scale should
light, indicating a very
"conductive" material
measurement.
b.
Proceed to Step 2, below.
c.
If the lowest decade LED
(10
3
UPPER Scale and 10
2
LOWER Scale) does not
light, the unit is not
functioning properly, or the
battery is dead.
