: lndicates SWR, Forward and Reflected Power.
: Used to select meter reading of AVG (ave-
rage power), NORMAL (normal PEP power)
or HOLD (PEP peak power).
: Used to select the power measuring range.
: Connect wlth soohms coaxial cable to trans-
mitter or transceiver.
Connect with Soohms coaxial cable to an-
tenna system.
Used to switch on/off the built-in lamp.
Connect to a 6-24V DC power supply to
measure PEP Peak Power ahd to illuminate
the lamp. Observe correct polarity, or damage
will occur.
The built-in sensor is used at the "lNT"
position, and the optional remote sensor at
the "EXT" position.
Connect to the remote sensor cable.
Used to hold a 006P battery.

IOPERATION
AVG lndicates RMS power of FM or continuous wave signal and
SWB.
NORMAL : lndicates approximate average Peak Power ol SSB signal.
HOLD : lndicates maximum Peak Power of SSB signal.
(Battery, OO6P gv,or DC power must be connected for meter to function
PEP operation.)
(1) Select the Mode switch to "AVG" position.
(2\ Please refer to OPERATION of NS-660 series meters._.
t) Measuring PEP power
(1 ) Connect the DC power socket to a DC power supply (6-24V) using
the cable provided.
(2) Turn the Mode switch to either "NORMAL" or "HOLD" positlon.
(3) When the transmitter is operated and the switch is in the
"NOBMAL" position the meter needle indicates average PEP of the
SSB signal. ln the "HOLD" position the true maximum PEP is
indicated.
x ln the "NORMAL" and "HOLD" positions while measuring forward
PEP, there is no indication of reflected power.
x During the various SSB transmission modes, as shown in the table
left, the meter reading of AVG and PEP will differ. Therelore, when in
the SSB transmit mode, before switching the mode switch from AVG
to PEP (NORMAUHOLD), make certain that the meter power setting
is correct. Otherwise, the meter needle will go off-scale, resulting in
damage to the instrument.
T CAUTIONS
X The meter movements are highly sensitive. Prevent mechanical
shock and vibration.
Measuring power with a poorly matched antenna or disconnecting the
output ol the bridge while operating may damage the meter.
Do not leave the meter lamp on if the meter is powered by battery.
Weak battery may cause measuring error or other malfunctions.
Reset meter needle by changing the Mode switch to the "NOBMAL"
and back to "HOLD" position il you wish to use the HOLD posilion
repeatedly. (NS-660P only)
