BK Precision 177/V-95 User Manual

Additional aclvantages
of the VTVM
in solid
state measurements are:
A
t/2
volL
full scale sensitivity
range which
permits
the accurate reading of the
fractions
of
a volt,
(which
are often applied between
base and emitter of transistor
devices).
'I'he
VTVM
input impedance
is important, so that
the connecting of the
meter does
not cause
false readings due to current injection in
the transistor base.
Other advantages in
the high impedance characteristics of the VTVM include
the
ability to acculately measure
voltages, without upsetting circuit operation,
on
AGC
lines,
high impedance osciilator
grid
and other
grid
circuits, insulation
resistance
measurements.

The AV-IA
RF
PROBE
enables
the
operator
to make measurements of
sine
wave
voltages
at frequencies
up
to 250 MHz.'rhis probe
employs
a
crystal
diode
which
is usecl
as a half
wave
rectifier.
The half
wave rectifier circuit
develops a
DC voltage
proportional
to the
peak
value
of
the sine wave input
signal.
A
cali-
brating
resistor
converts
this
peak
reading
to
the
proper
reading
on the
VTVM.
The
AV-2A
HIGH
VOLTAGE
MULTIPLIER
PROBE
has been
developed
as an
Accessory
item
(available
at
your
distributor)
to extend all DC voltage
ranges
of
your
VTVM
by a factor
of 100.
The heavy
duty
plastic
handle
and
safety-type connector
insures maximum
operator
safety. Two
oversized
flashover
guards
protect
the operator's hands
from
leakage
at the test
point
on the
probe
head.
One
of the most
u:;eful applications
of the AV-2 High
Voltage Probe
is
the
measurernent
of 2nd anode
voltage
in TV sets.
