PRECAUTIONS FOR PERSONAL
AND INSTRUMENT SAFETY
1. Read these instructions thoroughly and follow
them carefully.
2. In many instances you will be working with dangerous
levels of voltage and/or current, therefore,
it is important that you avoid direct contact with
any uninsulated, current-carrying surfaces.
Appropriate insulating gloves and clothing should
be worn.
3. Before connecting or disconnecting the instrument to
or from the circuit to be tested, turn off all
power from the circuit.
4. Before applying transducer to circuit under test,
make certain selector switch is set to proper
range.
5. Before using any electrical instrument or tester
for actual testing, the unit should be checked on a
known live line to make certain it is operating properly.
6. If the instrument should fail to indicate, do not touch circuit
until you have checked to see that all instrument
switches are in proper position and instrument has been
checked on a known live circuit.
IMPORTANT: Failure to follow the instructions or to
observe the above precautions may result in personal
injury and/or damage to the instrument and/or
accessories.

INTRODUCTION
Models PAVA83-12 and PAVA83-12-T can record single phase
volts or amps on one chart. Selection of variable is done by mov-
ing the AMP/VOLT switch to the desired position. Range selection
of variable to be recorded is done on the recorder panel for volts
and on the transducer for amps.

ZERO ADJUSTING
With chart drive switch in “OFF” position (see fig. 1) exposing
the word “OFF,” check mechanical zero setting of pointer (see
fig. 2) before making any electrical connections to the instru-
ment. If adjustment is necessary proceed as follows:
a) Remove top cover-pull bottom ledge of frame toward you
and lift. See fig. 3 or 4.
b) With strip chart roll not in recorder, locate star wheel. See
fig. 5 or 6.
¢) Apply finger to star wheel and turn until pointer lines up
with zero mark at the extreme right of scale. See fig. 2.

LOADING AND UNLOADING CHART PAPER
ON TAKE-UP MODELS
1. Move chart drive switch to OFF position exposing the word
“OFF” See fig. 1.
2. Remove top cover. See fig. 3.
3. To insert or remove chart paper, place recorder in horizontal
position and press the release button in the direction shown in
fig. 10. Raise the recorder mechanism to a vertical position until
it locks. Remove feed shaft A (see fig 9) and place chart roll on
spindle. Remove tape on roll and retain tape for securing chart
on take-up spindle D. Unroll about 12” to 15” and route paper
over top edge of scale plate B underneath glass, over the
sprocket wheels, to the
rear and over the idle roller C up to the cardboard bobbin mount
ed on the take-up spindleD. Secure edge of chart to bobbin with
tape. Make sure the sprocket holes in the
paper engage the sprocket wheels. Be sure
that feed control is tight and in the right posi-
tion. The word “on” must be visible. Press in
the idle roller extension C to allow the recor-
ding mechanism to move back down into the
case and lock into position. Replace cove by positioning the “U”
bend onto the plastic projections and snap front down. Make sure
chart paper is not binding with the cover in place. For “non-take -
up” recording, route chart through bottom slot as shown in fig. 9.
Fig. 10
. To remove chart from take-up spindle D, move the latches away
from the take-up spindle. Turn knurled knob on spindle D until the
siot in the take-up drive pulley at the opposite end of the spindie
is lined up with the slot in the side frame of the recorder. Slide the
spindle and chart up and out of the slots in the side frames of the
recorder. Remove tape from chart and bobbin.
‚ То unioad chart paper from recorder turn chart drive switch off,
exposing the word “OFF” See fig. 1. Follow 4 above. Remove
chart from feed shaft A and pull paper through recorder.
SELECTING CHART SPEED ON TAKE-UP MODELS
. To select chart speed, energize recorder with proper line volt
age and frequency. Raise recorder to vertical position (see load
ing and unloading chart paper on take-up models). Move chart
drive switch to “ON” position exposing the word “ON”. Make
sure switch clicks into detent (see fig. 11) Set all three speeds
to “OFF” position and tighten (see fig. 9). Move desired speed
knob (1, 12 or 24) to “ON” position. Tighten while Keeping pres-
sure on gear mechanism.
. Press in the idle roller extension C to allow the recording mech-
anism to move back down into the case and lock into position.
Replace cover by positioning the “U” bend onto the projections
above the chart well opening. Make sure chart paper is not
binding with the cover in place. For “non-take-up” recording
route chart through bottom slot as shown in figure 9.
HOW TO USE AS A RECORDER
. Chart drive switch must be in “OFF” position (exposing the word
"OFF”). See Fig. 1. |
. Remove top cover. See fig. 3 or 4. Adjust zero setting with
power off and recorder not connected to any voltage or current
source. (See Zero Adjusting).
. Load chart paper. See fig. 7 or 9. Replace cover by positioning
the “U” bend onto the metal projections of the chart well (non
take-up) and onto molded plastic projections for take-up
recorder and then snap the front down. Make sure paper is not
binding with cover in place.
. For Voltage Recording- Set range selector switch to appropriate
voltage range. Move “AMPS-VOLTS” switch to “VOLTS” posi-
tion. Attach adaptor extension lead (supplied) if needed, to
meter cord and plug into recorder receptacie. Connect to volt
age source to be measured.
. For Current Recording- Connect current
transducer to terminal on right hand panel of recorder. Observe
color coding of terminals.
Caution: If correct polarity is not observed, meter will read down
scale and not function. Move "AMPS-VOLTS” switch to “AMPS”
position. Set range switch on current transducer to appropriate
position. Clamp current transducer around one leg of line going
to the load.
6. Plug power line cord into recorder line receptacle and connect to
proper line voltage and frequency.
7. Push chart drive switch to “ON” position (exposing the word
“ON”). Make sure it clicks into detent position which locks it into
place. See fig. 11.
. Mark time of start on strip chart. See fig. 8. .— e
9. Secure recorder in horizontal or vertical position. 4

READING STRIP CHARTS
Strip charts have more than one scale. REad on the scale that cor-
responds to the range you are using. If the particular range you are
using does not appear on the chart, use a scale with numbers that
you can easily convert to the range you need. (example: Using
chart 850A, with recorder on 0-50 amp range, read on the 0-5 scale
and multipiy by 10).
HOW TO USE AS AN INDICATING METER
Follow steps 1,2,4,5 and 6 of “How To Use As A Recorder.” With
chart paper removed, read directly on scale plate.
SERVICE
Serial number is stamped in over right hand corner of the scale
plate.
