Usefull Save/Load function helps work go faster
The
3237, 3238
and
3239
are equipped with a variety of
functions that help minimize tact time in production lines.
For details, see page 2.
Does not apply at resistances higher than 2MΩ, or LPΩ higher than 200kΩ (see page 5).
For the 3238 and 3239's frequency function gate time, see page 5.
* Approximately 55 ms required for self-calibration at 30-minute intervals.
■
True RMS value measurement
Both the
3237
and
3238
use true RMS measurement
for determination of distorted waveforms. In fact,
HIOKI
guarantees accuracy of the
3238
and
3239
for AC voltage of
10 Hz to 300 kHz, and AC current of 10 Hz to 30 kHz.
For specifications, see pages 5 and 6.
■
Low power resistance measurement function
prevents sample deterioration
The
3237, 3238
and
3239
use a low power Ω function to
minimize sample degradation when measuring resistance.
With this function, open terminal voltage never goes over 0.45
V DC, and measurement current never surpasses 100 µA DC.
For specifications, see pages 5 and 6.
■
Interface supports full remote operation
Measurement can be automated by using a controller to operate
the
3237
or
3238
through the GP-IB or RS-232C interface.
For details, see page 3.

■
Reliable resistance measurement
using the 4-terminal measurement method
Using 4-terminal resistance
measurement, which is
unaffected by variables
such as measurement lead
wiring resistance, the
3239
displays outstanding
resistance measurement
capabilities.
