2.2 Connecting the Cables
2.2 Connecting the Cables
2.2.1 Connection Preparations
Read the following carefully before making connections.
For voltage measurement
About maximum input ratings of input modules and cables
• The maximum input voltage is the lesser rating of either the input module
or the cable to be used. Do not measure if this voltage would be
exceeded, as damage the instrument or a serious accident may result.
Example: When connecting the Model 9197 Connection Cord (500 Vmax)
to the Model 8936 Analog Unit (400 Vmax), the maximum input voltage for
measureme nt is 400 V DC.
For details of maximum input voltages, refer to "1.1 Product Overview"
(⇒ p. 5)
• When connecting clip-type test lea ds to live termin als, be very ca reful to
avoid accidentally shorting conductors together and causing a serious
accident.
• When measuring voltage in a power line, connection cables shou ld only
be connected to the sec onda ry side of a breaker, so the breaker ca n p revent an accident if a short circuit occurs. Connections should never be
made to the primary side of a bre aker, because unrestricted c urre nt flow
could cause a serious accident if a short circuit occurs.
• Do not permanently connect the device in an environm ent wh ere voltage
surges exceeding the maximum input voltage may occur. Failure to
observe this precaution could result in damage to the device and personal injury.
and "Chapter 5 Specifications" (⇒ p. 83).
• Do not use cables other than those specified by Hioki. The specified
cables include insulated BNC plugs to avoid electric shock. An uninsulated BNC plug may cause electric shock or damage to the BNC jack.
• Do not connect a cable to the instrument while it is connected to the
object to be measured. Otherwise, an electric shock accident may occur.
Use only the specif ied c onn ec tio n c or ds . Usi ng a non -spe ci fie d c abl e ma y r es ul t
in incorrect measurements due to poor connection or other reasons.
Using cables with BNC connectors
When disconnecting the BNC connec tor, be sure to release the lock be fore pulling off the connector. Forcibly pulling the connector without releasing the lock, or
pulling on the cable, can damage the connector.
When using the Model 8958 16-Ch Scanner Unit together with other
input modules
Do not attempt to measure the same signal with the 8958 and another input
module at the same time. Channel switching noise from the 8958 may affect
the other input module.

2.3 Connecting Clamps
Because it measure s only volta ge input, cu rrent is not m easured d irectly by this
instrument.
Use a clamp that provides voltage output for current measurement.
Refer to "1.3 List of Input Modules, Cables, Probes and Clamp Combinations"
(⇒ p. 11) for compatible combinations of Hioki clamps and input modules.
Refer also to the clamp’s Instruction Manual for clamp-specific details.
Preparations for Using Clamps
Connect the clamp-on sensors to the instrument first, and then to the
active lines to be measured. Ob serve the follow ing to avoid elect ric shock
and short circuits.
• To avoid short circuits and potentially life-threatening hazards, never
attach the clamp to a circuit that operates at more than the maximum
rated voltage, or over bare conductors.
• Clamps should only be connected to the secondary side of a breaker, so
the breaker can prevent an accident if a short circuit occurs. Connections should never be made to the primary side of a breaker, because
unrestricted current flow could cause a serious accident if a short circuit
occurs.
• When the clamp sensor is opened, do not allow the metal part of the
clamp to touch any exposed metal, or to short between two lines, and do
not use over bare conductors.
29
2.3 Connecting Clamps
To avoid electric sho ck when measuring live lines, wear appropriate protective gear, such as insulated ru bber gloves, boots and a safety helmet.
• To prevent dam age to the instr ument and cla mp, never co nnect or dis connect
a sensor while the po wer is on, or whi le the sens or is clamped around a conductor.
• Be careful to avoid dropping the clamps or otherwise subjecting them to
mechanical shock, wh ich could damage the mating surfa ces of the core and
adversely affect measurement.
• Measurements are affected b y the combine d accuracy of this instrum ent and
the clamp.
• The measured value is displayed as voltage [V], although this can be
converted for display as current [A] using the Scaling function.
See "5.4 Converting Input Values (Scaling Function)" in the Instruction Manual
• In the following cases, scaling setup is necessary:
(1) When using a clamp with a voltage measurement input module other than
the Model 8940 F/V Unit
(2) When connecting a clamp to the Model 8940 F/V Unit without the Model
9318 or 9319 Conversion Cable

• Model 9320-01 Logic Probe
Refer to the instruction manual supplied with the logic probe for specific details.
Do not connect logic probes other than those supplied by Hioki to the logic
inputs.
For users of the following legacy models:

2.6 Connecting Logic Probes
Before connecting a logic probe to the measurement object
To avoid electric shock and short circuit accidents or damage to the instrument, pay attention to the following:
• The ground pin in the LOGIC connector (plug) of the Model 9320-01 and
9327 Logic Probes (and legacy Models 9306 and 9320) is not isolated
from this instrument’s ground (common ground).
Use grounding-type polarized power cords for the measurement object
and this instrument, and obtain power from the same mains circuit.
Connecting to different mains circuits or using a non-grounding power
cord may cause damage to the measurement object or this instrument
because of current flow through the logic probes resulting from potential
difference between the grounds of the different wiring systems.
To avoid these problems, we recommend the following connection procedure:
Connect this instrument to the same
outlet as the measurement ob ject using the (supplied) grounding polarized power cord.
Connect the measurement object’s
ground to the GND terminal of this instrument. (Always obtain power fro m
the same mains circuit.)

Connection Procedure
2.6 Connecting Logic Probes
• Maximum logic probe input voltages are as follows. Do not measure if
the maximum voltage would be exceede d, as damage the instrumen t or
personal injury may result.
Model 9327 Logic Probe: +50 VDC
Model 9320-01 Logic Probe: +50 VDC
Model 9321-01 Logic Probe: 250 Vrms (HIGH range), 150 Vrms (LOW
range)
• Do not allow the metal tip of a logic probe to cause a short between conductors on the measurement object. Never touch the metal tip of a probe.

• When the ambient temperature changes rapidly:
Loss of thermal e quilibrium may result in measur ement errors. If this occurs,
allow about an hour for the equip ment to accl imatize to the new te mperatur e,
then take measurements after thermal equilibrium is achieved.
• In an environment wit h fluctua ting ambie nt temp erature, when r ecordi ng for a

3.10.17 Executing Zero Adjustment
The input module can apply an internal offset to set the reference potential of the
instrument to zero volts. Adjust ment applies to the currently selected range.
Before executing zero adjustment
• Turn power on and wait 30 minutes to allow the internal temperatu re of the
input module to stabiliz e. (Some input modules may require one hour warmup.)
• Zero adjustment cannot be performed while measuring.
• Key operations are not accepted while zero adjustment is executing.
To execute zero adjustment
Move the cursor to the [Zero-Adjust] button, and select F1 [Execute].
Zero adjustment can be performed from the CH SET dialog on the Wavefor m
screen.
Zero adjustment is not applicable to the following modules:
• The [Temp] mode of the Model 8937 Voltage/Temp Unit
• Model 8939 Strain Unit
• Modes other than [Voltage] and [Current] of the Model 8940 F/V Unit
• Model 8958 16-Ch Scanner Unit
In the following cases, zero adjustment should be executed again.
• After an input module has been removed or inserted
• After power has been turned off and on
• After complete reinitialization
• When ambient temperature has changed significantly
The zero position may have drifted.
When using the Model 8958 16-Ch Scanner Unit, zero position adjustment of the
module from the System screen may be needed.
See "Scanner Unit Zero Position Adjustment" (⇒ p. 27)
3.10.18 Executing Offset Cancellation

77)
Before executing offset cancellation
Connect the pro be or c lamp to th e mea surem ent o bject and apply the input signal that is supposed to measure zero volts.
See "About input voltage during offset cancellation" (⇒ p. 77)
When also using scaling, execute offset cancellation before setting the scaling.

3.10 About Setting Contents
Offset cancellation cannot be executed in the following cases:
• When measuring other than voltage or current
• When the input voltage is more than ±10 divisions from zero
About input voltage during offset cancellation
The maximum input voltage and maximum rated voltage to ground are
unaffected by offset cancellation of an input voltage to zero volts. Therefore, careful attention is necessary during measurement.
A constant input voltage is required to execute offset cancellation.
If the input voltage is fluctuating, the offset to zero volts depends on the timing of
offset cancellation execution.
When input voltage is constant When input voltage is fluctuating
Offset voltage +V

The offset voltage set to display as
zero depends on the timing of offset
cancellation execution.
Offset cancellation
Offset cancellation is not reset even when power is t urned off. It is reset when
the input module configuration is changed (after an input module has been
inserted or removed).
If “Warning: Offset Cancel failed.” appears
This appears when executing offset cancellation if the input voltage is more than
±10 divisions from zero volts.
To avoid the warning, set the input signal within ±10 divisions of zero volts.
What is the difference between Offset Cancellation and Zero Adjustment?
Offset cancellati on adjusts for input sig nal bias if there is a potenti al difference
between the referenc e potential of the measurement objec t and the reference
potential (0 V) of this inst rumen t, so that the refe renc e potenti al of the measurement object appears as zero volts.
Zero adjustment se ts the input module’s int ernal bias so th e reference poten tial
of the instrument is zero volts.

• After an input module has been removed or inserted
• After the strain gauge transducer has been replaced
• After power has been turned off and on
• After performing a system reset
• When ambient temp erature has changed si gnificantly (the zero position may
drift)
If “Warning: Auto bal ance failed.” appears
