Sencore FE20 Level Meter
Hersteller:
Sencore
Modell: FE20
Datum: 1970
Kategorie: Messgeräte
Gruppe: Level Meter
Beschreibung: HI LO Meter
Informationen:
                                    As the state of the art in electronics progresses, more
transistors, FETs,
and integrated circuits are being used in radio, television,
and industrial
markets. Sencore engineers have kept up with todays pace and
have developed
a new Field Effect meter to meet the more demanding requirements
of solid state and integrated circuit servicing.
The FE20 HI-LO meter features new low AC and DC ranges of .
1 volts full
scale and alow power ohms circuit allowing for the first
time accurate re sistance
measurements in transistor and integrated circuits.
Just compare these features and see why the FE20 is the most
advanced
meter on the market today:
* High input impedance on all AC and DC ranges (15 megohm
DC, 12 megohms
AC).
* True peak to peak AC ranges.
* Zero center ranges on DC for solid state servicing.
* Db scale for audio and lab work.
* DC current ranges for general testing.
* Low power (low applied voltage) ohms ranges for solid
state servicing.
* Mirrored scale meter for greater accuracy in readings.
* Meter protected from overloads.
* Circuits protected from accidental application of wrong
voltages.
* All steel carrying case with cover for greater durability
and portability.
* Long life "C" cell power.
