1.1 Product Overview and Features
7
The instrument is an 8-channel, high-sensitivity ammeter for use in measuring
insulation resistance. It can perform insulation measurement of target objects
such as electrical insulators with high resistance values, measuring all 8 chan-
nels simultaneously at high speed. The instrument is designed for use in applica-
tions such as automatic insulation testing, particularly of capacitors.
This insulation measuring instrument requires an external measurement power
source to be provided by the operator. HIOKI offers a recommended power
source (Model SM7860 series Power Source Unit).

1.1 Product Overview and Features
Easy integration into automated testing sys-
tems
The instrument features a standard external I/O inter-
face, allowing contact check results and comparison
judgment results to be downloaded to other devices.
Additionally, external I/O can be used to easily change
target objects, making it easy to integrate the instru-
ment into an automated testing system.
High-speed insulation resistance measurement
The instrument is a high-sensitivity ammeter for use in in-
sulation resistance measurement applications. The time
from trigger activation to index output is as little as 7 ms.

8-channel simultaneous measurement
The instrument can measure 8 channels simulta-
neously, boosting production volume. This capa-
bility improves on previous HIOKI instruments,
which offered 4 channels.

Compatibility with high-
capacity capacitors
Range: 100 pA to 1 mA
The instrument features an ex-
panded current measurement
range to accommodate increas-
ingly high-capacity MLCCs, mak-
ing possible more accurate pass/
fail judgments.
Interface communications
The instrument can be connect-
ed to a control device and con-
trolled via either its GP-IB or RS-
232C interface. Measurement
data can also be downloaded.
Contact check for improved reliability
The instrument can check for poor contact with the ob-
ject under measurement using the capacitance detec-
tion method, and the results of this check can be
output from the instrument.
