PREPARATION FOR USE AND INSTALLATION
To charge the battery before use, use the power cord
appropriate for the mains (120 VAC cord supplied). Allow
approximately 8 hours for a full charge; the “BATTERY
CHARGING” LED will turn off when the battery is fully
charged. After charging, remove the power line cord,
although no harm will result if it is left plugged in. Note that
with a fully discharged battery, the charger may turn off after
a few minutes (because the rapid increase in voltage could
be interpreted as the fully charged condition). If that occurs,
unplug the power cord briefly and then plug it in again; the
unit should now charge for several hours.
WARNING
ALTHOUGH THE FRONT PANEL IS NORMALLY GROUNDED
VIA THE GROUND PIN OF THE POWER CABLE, IF THIS
CONNECTION IS FAULTY AND IF THE HIGH SIDE OF THE
POWER CABLE IS SHORTED TO THE PANEL, THE PANEL
COULD POSSIBLY HAVE MAINS VOLTAGE ON IT; SO DO
NOT TOUCH THE PANEL WHEN AC POWER IS
CONNECTED.
Connection to Resistor under Test
Connect the resistor under test to the 4 front-panel binding
posts as follows:
For
4-wire operation
, connect the +I and +E binding
posts to one end of the resistor under test and -I and -E to
the other end of the resistor under test.
For
3-wire operation
, cI and +E to one side of the
3-wire RTD and connect –I to the other side of the RTD. –E
is not connected.
For 2-
wire operation
, use +I and –I, +E and –E are not
connected.
WARNING
DO NOT TOUCH THE BINDING POSTS WHEN THEY ARE
CONNECTED TO EXTERNAL CIRCUITS. LETHAL
VOLTAGES MAY BE PRESENT AT THESE POSTS.
