NOTE
When bombs are first immersed in the bath, an equal
amount of water will drain out overflow pipe.
Next, check the thermoregulator.  Inspect the
regulator closely, observing for presence of gas
bubbles in mercury column.  If bubbles or separa-
tion of mercury in column exist, heat bulb gently
until bubbles are driven up into the expansion
chamber.  Cool slowly in a vertical position
allowing mercury to receed slowly to form a solid
column without bubbles or separation.
b.  To calibrate the thermoregulator, immerse regulator in the
bath at a temperature lower than that at which the bath is to be
regulated.  Place a calibrated ASTM No. 18F thermometer in the bath.
Bring bath temperature up to 96 degrees F to 98 degrees F, rotate the
micro-set magnetic coupler until the indicator light on the control
box is out; rotate the magnetic coupler until indicator light is on;
continue making minor adjustments until the bath temperature is
maintained at the desired temperature (100 degrees F +0.2 degrees F
or -0.2 degrees F).

Battery Replacement.
a.
(1) Two batteries are used inside the case to supply power
for resistance measurements.
One is a 1.5 volt D cell and the other
is a 9-volt battery.  When it is no longer possible to adjust the
pointer to zero for the RX1 and RX1OO ranges, replace the  1.5 volt
cell.  When it is no longer possible to adjust the pointer to zero on
the RX1O,OOO range, replace the 9-volt battery.
(2) To install or replace a battery, remove the cover to
the externally accessible battery compartment by loosening the single
captivated screw.  A small coin may be used to loosen the screw.
