Operating Precautions
: 0 to 40°C at 80%RH or less (non-condensing)
: 23±5°C, 80%RH or less (non-condensing)
Avoid the following locations that could cause an accident or damage
to the device.
Exposed to direct sunlight
Exposed to high temperature
Exposed to water, oil,
other chemicals, or
solvents
Exposed to high humidity or condensation
Exposed to high levels of particulate dust
Subject to vibration

Near electromagnetic
radiators (e.g., high-frequency induction heating systems and IH
cooking utensils)
• Do not slant the device or place it on top of an uneven surfa ce. Dropping or
knocking down the device can cause injury or damage to the device.
• Ventilation holes for heat radiation are provided on the si de and re ar panels of
the device. Leave sufficient space aroun d the ventilation holes and install t he
device with the holes unobstructed. Installation o f the device with the venti lation holes obstructed may cause a malfunction or fire.

Operating Precautions
Installing To prevent overheating, be sure to leave the specified clearances around the
unit.
• Vents must not be obstructed.
• When rack-mounting the dev i ce, fans must be in stalle d abov e or on top of the
rack to ensure proper ventila tion. Be sure that the rack is adequately ven tilated so that the i nternal temperature remains at o r below 40°C. Continued
use of the device in a high-temperature envir onment will shorten its servic e
life. Keep the temperature as low as possible.
Handling the Device
• Do not allow the device to get wet, and do not take measurements with
wet hands. This may cause an electric shock.
• Touching any of the high-voltage points inside the device is very danger-
ous. Do not attempt to modify, disassemble or repair the device; as fire,
electric shock and injury could result.
• To avoid damage to the device, protec t it from physic al shock whe n transport-
ing and handling. Be especially careful to avoid physical shock from dropping.
Failure to observe the following precaution may result in bodily injury.
• The device weighs approxi mately 45 kg (SM7860-07, -27: approximately 32
kg). It should be move d by at least two people, who should grip it using the
handles on the left and right sides.
• The device is he avy. When transporting it, foll ow your company's workplace
safety standards to assure safety (for example, by wearing non-slip gloves and
protective footwear).
Handling the Cords
5
Operating Precautions
Before using the device, make sure that the insulation on the Connection
Cable is undamaged and that no bare conductors are improperly exposed.
Using the de v i ce i n s u c h conditions could cause an e lec t r i c shock, so con tact your dealer or Hioki representative for replacements.
• Avoid stepping on or pinching cab les, which could damage the cable insulation.
• To avoid breaking the cables, do not bend or pull them.
• To avoid damaging the power cord, grasp the plug, not the cord, when unplugging it from the power outlet.
• Keep the cables we ll away from heat sources, as bare c onductors could be
exposed if the insulation melts.
Use only the specified connection cables. Using a non-specified cable may
result in incorrect measurements due to poor connection or other reasons.
Before Connecting
• Before turning the device on, make sure the supply voltage matches that
indicated on its power connector. Connection to an improper supply voltage may damage the device and present an electrical hazard.
• To avoid electrical accidents and to maintain the safety speci ficat ion s of
this device, connect the power cord only to a 3-contact (two-conductor +
ground) outlet.
T o ensure measurements are accurate,
• Warm up the device an hour or more before use.
• The device should be calibrated once a year.

1.1 Product Overview and Features
Overview Chapter 1
1.1 Product Overview and Features
The SM7860-01 to -07 and SM786 0-21 to -27 ar e power supp ly units d esigned
for use with the Model SM7810 or SM7810-20 Super MΩ HiTester. They support
bipolar, multi-channel output and are compatible with multi-channel systems.
Used in combination with the Model SM7810 or SM7810-20 Super MΩ HiTester,
they are ideal for use in automated testing and measurement of capacitors.
Bipolar, multi-channel output
The device delive rs an 8-channel, positive/negative power supply, allowing an
optimized test ing line to be built using th e smallest possible number of power
supplies.
7
Independent on/off output switching and current limitations
for all channels
Since each channel has its own output on/off switch, it is possible to control voltage application without an external circuit (allowing charging and dis charging).
Use of semiconduc tor switches elimina tes the need for mainten ance. Additionally, the ability to limit current (to 50 mA) for individual channels means the measurement of other channe ls won't be affected when a target workpiece has a
short.
Output current capacity: 50 mA/channel
High-capacity capacitors can be charged rapidly, and the number of charges can
be reduced.
Output voltage: 1,000 V/channel
Devices are available with output voltages of up to ±1,000 V.
Standard interfaces
Devices ship standard with external I/O, GP-IB, and RS-232C interfaces for
sequencing. Interfaces are used to configure and power the devices.
