Carefully inspect instrument construction. Be sure all wires and components have
been properly connected and soldered. Check positioning of wires and components
for possible short circuits. Turn the instrument over and shake out any loose
solder or wire cuttings.
PRELIMINARY TEST
Plug the T-65 line cord into a 117-volt, 60-cycle AC source. Set power switch to "ON".
Meter pointer should deflect to approximately mid-scale.
"ADJUST LINE" control should
move pointer to left and right. DepreSSing "READ METER" button should cause meter pointer
to fall back to "0" on scale.
H
the instrument fails to respond as indicated or if signs of trouble
such as smoke or overheating appear, disconnect the line cord from the power source and check
for wiring errors and short circuits. Further assistance in locating trouble may be found in the
section "COMPLETE CHECK-OUT PROCEDURE".
H
the instrument responds in the manner indicated, proceed to !1CALIBRA TION PRO
CEDURE."
CALIBRATION PROCEDURE
,/1.
, /
With power "OFFlt, zero adjust the meter in the position
it
will be used (usually horizontal).
)1: Use an accurate, high-impedance YOM, like PRECISION Model 120 or 110 or PACO Model
M-40. Set YOM to 6vAc or higher. Clip positive
(+)
YOM test prod tip to lug 6 (gray-yellow
lead) on "A" switch. Clip minus (-) YOM test prod tip to minus (-) end of the 100-mfd ca
pacitor. Control and swit-ch settings do not matter.
