How to Test
Perform the performance test in an area free from dust, vibration, and noise, and under the following envi-
ronmental conditions:
Temperature:
23
C
5
C
Relative humidity: 70% or less
Warm-up time:

The performance of this instrument (8250A) can be checked by performing a current measurement test.
This instrument allows the different internal measurement path (sensor series path) according to the sensor
series (823* or 821* series) connected to this instrument. Because the specifications are different between
each sensor series, switch the path and perform the test.
The path can be switched by replacing the TRIAX-12pin conversion adapter A (for the 823* series) with
TRIAX-12pin conversion adapter B (for the 821* series).
Procedure
1. Connect the 823* series sensor to this instrument and turn on the power.
2. By pressing the
