I APPLICATIONS
Xz
Portable potentiometer Type 703 is an instrument for measuring
the DC electromotive force. Its range is from 0--71 millivol
a tS.
This portable potentiometer is especially suitable for direct
measuring of thermocouples, for comparison against standard thermo-
couple, or of calibrating temperature indicating millivoltmeters.

The ~ measuring part comprises a range selecting switch and a
L
slide wire. The range switch has six ranges, and the slide wire
ange-,K~ of 0_-i1 MV with 0.1 MV per division,
had a tota. range of 11 L.1. ,,,~.-
2. The working current of the potentiometer is 3 MA and is adjusted
to this value by comparison with an internal standard cell.
3. The current adjuster comprises a two-ganged rheostat. (fine and
coarse rheostats in series). It is so arranged that when turning
the knob in one direction the fine and coarse rhostats rotates
together and coarse adjustment is obtained; when turning the knob
?
in the opposite direction only the fine rheostat rotate and thus
a finer adjustment is obtained.
ointer galvanometer is used for null indicating.
4, A P b
A Protecting resistor is inserted in series with the standard cell
circuit. When the voltage of the battery falls beyond the adjusting
limit of the rheostat, this resistor will protect the S.C. from being
damaged by over current.

IV COMPLETE EQUIPMENT
The instrument is supplied with following parts:
1. Standard cell (installed in the cabinet) 1 pc.
2. Dry cells (installed in the cabinet) 3 pcs.
3. Instruction Manual 1 pc.
4. Cartificate of Test 1 pc.
V OPERATION
1. To Measure E.M.F.
1) Release the pointer of the gal by pushing the button
backward. Adjust the zero adjuster until the pointer indicates
in the zero position.
2) Connect the unknown E M F. to the posts X, or X2. Set the
lever switch A to "S.C.". Adjust the current adjuster until
the galvanometer indicates zero. The working current is
then adjusted to the rated value.
3) Set switch A to "X", switch B to
"X
or "X2", balance the
potentiometer by turning the range switch and slide wire
dial until the gal. indicates zero.
4) Reading on the range switch plus reading on the slide wire
dial will be the value measured.
5) Push the lever switch to the middle position when the instru-
ment is not in use. The galvanometer should also be locked.
2. Change battery if the current adjusting rheostat cannot set the
gal, to zero position.
3. For calibrating millivoltmeters, connect as shown in Fig. 2

potentiometer
~ ~ ,i
For convenience of ~ checking ordinary thermocouple against a
standard element, connect these two couples to the posts "Xi" and
"X2" respectively. After adjusting the working current set lever
switch 1 t X, and precede to measure the couples alternately by
setting the switch B to "Xi" and "X2". g Thus any error due to time
delay in changing thermocouples may be avoided.
5. The wooden case of the instrument should only be placed in h
e
positon supported by the rubber plugs. To place the case in any
other positon will damage the standard cell inside the instrument.
6. The instrument should be laced in a surrounding temperature
of + 5? to + 35?C, relative humidity of 80
y %. Avoid any direct
sunlight.

FIG 1
CONSTRUCTION
A knob at right of the panel is used to vary l the position of the galva-
nometer circuit in the double slide wire. and therefore the reading of the
dial. The galvanometer is installed at the left of the panel with a ratio block
in the lower part of the meter.
(1) The galvanometer
A adjusting zero cap (7 in fig. 2) is mounted on the upper part of the galva-
nometer. Care should be taken not to turn violently to avoid damage
of the adjuster. A button (9 in fig. 2) is provided to lock the pointer
of
the galvanomenter. To lock the pointer, push the button forward to
unlock, push backward.
(2) Ratio Block
Two plugs u
o pgs are used to change the ratio of the bridge (10 and 11 in fig. 2
Plugs should be pressed firmly to ensure minimum contact resistance.
(3) Slide Wires
The reading dial comprises two slide wires. Turning the knob of the dial
will vary the position of the galvanometer in the slide wires.

GEN-ERAL USE: Precision pressure measuring apparatus for
steam boilers of all sizes, vehicle oil compressors, air comressors
etc. The measurement result can be easily read by the scales indica-
ted.
APPLICATIONS: A. Suitable for measuring pressure of slow flow
and even liquid and atomosphere, but not suitable for measuring
explosive matters and crystallized substances.
B. The temerature of the liquid and atomosphere to be measured
should range from-20?C to 60?C.

INSTALLATION:
A. If the gauge is to be installed near the boiler with a surface tempera
ature within 100?C. It should be equipped with curved tubes.
B. Should the swfa?c .,e temperature be over 100?C, tubes of pro Portionate length is to be installed.
C. The distance from the surface of the gauge to the boiler should be
