Model 252 / 253
252, 253 Digital Impedance Meters
- Automatic L, R, C, G and D measurements
- Basic accuracy 0.25%
- Auto-ranging version, 253
- Test frequency 1 kHz
- Shielded four-terminal connections to unknown
- Optional rechargeable battery power pack
TEGAM Models 252 and 253 are used for evaluating and inspecting components.
These meters provide direct, digital display of inductance, capac it ance,
resistance, conductance and dissipation.
They have the versatility and basic measurement accuracy (0.25%), to satisfy
demanding engineering and inspection applications, while being extremely easy
to use.
Simply push the button for the desired function, set the range and connect to
the unknown. True fourterminal connections are ensured by the standard Kelvin
Klip® test leads. The measurement is displayed on the large 3½-digit readout.
The Model 253 has all of the above characteristics, an autoranging feature,
and includes one additional measurement range for C and G.
An optional battery power pack (252/SP2596 or 253/SP2598) is available on both
versions. This allows these meters to be used with line power when available
and unplugged when convenient or necessary.
