1.1 Product Overview and Features
Operating Principles and Block Diagram
The instrument is an 8-channel, high-sensitivity ammeter for use in measuring insulation resistance. After
connecting the dedicated external power source to the voltage input terminal (A) and applying voltage to the
object under measurement from the voltage output terminals (OUTPUT), current is measured at the current
input terminals (INPUT). The resistance value is then calculated from the measured current values and the
set measurement voltage values.
The measurement block performs current/voltage conversion using charge measurement type current-voltage
converters (B) that integrate input current values and A/D converters (C). This method allows precise measurement of minute currents by using long integration times.
Having been converted into digital data, measurement block output is sent to the control block (D) memory.
The control block (D) performs arithmetic processing on measurement data that has been input to its memory
and sends output to the instrument’s LCD screen and interfaces.

Output Queue data information
Standard Event Register Information
Each of these bits corresponds to a specific event register
Overview of Service Request Occurrence
RS-232C reads the status bytes to find out the status of the instrument.
The instrument adopts the IEEE488.1-1987 defined status model for parts
related to the serial polling performed by the service request function. A trigger
for generating a service request is called an event.
27
4.5 Communication Methods
The Status Byte Register contains information about the event registers and the
output queue. Required items are selected from this information by masking with
the Service Request Enable Register. When any bit selected by the mask is set,
bit 6 (MSS; the Master Summary Status) of the Status Byte Register is also set,
which generates an SRQ (Service Request) message and dispatches a service
request.
For RS-232C, bit 4 (MAV message available) of the status byte register is not
set.
Page 31
28
4.5 Communication Methods
Status Byte Register (STB) ______________________________________
A status byte register is an 8-bit register output from the unit to the controller during serial polling. If even one of the status byte register bits enabled by the service request enable register changes from "0" to "1" the MSS bit becomes 1. At
the same time, the RQS bit also becomes "1" and a service request is generated.
The RQS bit is always synchronized with the service request and only read and
simultaneously cleared upon being serial polled. The MSS bit is only read by an
"*
STB?" query and is not cleared until the event is cleared by a command such
as a "*
CLS" command.

4.7 Listener Specification Precautions
4.7 Listener Specification Precautions
Input buffer size
Multiple command messages can be transferred at once by joining them with
message separators. Since the instrument provides an 128-byte input buffer, the
instrument is unable to receive message strings in excess of 127 characters in
length. In this case, the entire command will be ignored (discarded), and the
Error Register's MLE (Message Length Error) bit will be set.
Reading from the output buffer
The output buffer uses a FIFO design, with older data being read first. Consequently, the read value may differ from the expected value under certain circumstances, for example if no response is acquired after issuing a query.
Additionally, the output buffer is 511 bytes in size. If data in excess of 511 bytes
is written to the buffer, it will be discarded, and the Error Register's QYE (Query
Error) bit will be set.

5.1 External Input/Output Connector and Signals
External Control Chapter 5
This chapter describes how to use the EXT I/O connector on the rear of the
instrument to control the device.
5.1 External Input/Output Connector
and Signals
To avoid electric shock or damage to the equipment, always observe the
following precautions when connecting to the EXT I/O connector.
• Always turn off the power to the instrument and to any devices to be con-
nected before making connections.
• During operation, a wire becoming dislocated and contacting another
conductive object can be serious hazard. Ensure that the cable is
securely attached to the EXT I/O connector.
• Ensure that devices and systems to be connected to the EXT I/O connec-
tor are properly isolated.
To avoid damage to the instrument, observe the following cautions:
• Do not apply voltage or current to the EXT I/O connector that exceeds their ratings.
• When driving relays, be sure to install diodes to absorb counter-electromotive
force.

7.1 Troubleshooting
Inspection and Repair
Touching any of the high-voltage points inside the instrument is very dangerous. Do not attempt to modify, disassemble or repair the instrument; as
fire, electric shock and injury could result.
59
If the instrument seems to be malfunctioning, confirm that the cables and fuse
are not open circuited before contacting your dealer or Hioki representative.
Transporting
Pack the instrument so that it will not sustain damage during shipping, and
include a description of existing damage. We do not take any responsibility for
damage incurred during shipping.
Replaceable Parts and Operating Lifetimes
Useful life depends on the operating environment and frequency of use. Operation cannot be guaranteed beyond the following periods.
For replacement parts, contact your dealer or Hioki representative.

7.2 Replacing the Power Fuse
• To avoid electric shock, turn off the power switch and disconnect the
connection cables before replacing the fuse.
• Replace the fuse only with one of the specified characteristics and volt-
age and current ratings. Never use unspecified fuses and never use the
instrument after the fuse holder has shorted. This will damage the instrument and cause injury.

Appendix 2 Rack Mounting
Appendix 2 Rack Mounting
You can remove the screws on the sides of the instrument and attach rack
mounting brackets.
To avoid damage to the instrument or an electrical accident, be sure to
observe the following precautions on using screws.
• Ensure that the screws used to attach the rack mounting brackets to the
sides of the instrument are not screwed into the instrument more than
10 mm.
• If the rack mounting brackets are removed, be sure to use screws identi-
cal to the ones used originally.
(M4 × 10 mm)
When rack-mounting the instrument, place it on the shelf specified by the rack
manufacturer or on a support angle. Mounting it on a rack using only the four
front screws may damage the rack-mount bracket.
