3.1 Usage Precautions
General Handling Precautions
●When carrying the instrument
Turn off the power to the object under test. Turn off the power to the
instrument and unplug the power cord from the outlet if you are using an AC
adapter. Then, disconnect all lead cables from the instrument. When carrying
the instrument, use the carrying case.
●Keep input terminals away from electrically charged articles as they may
damage the internal circuitry.
●Do not allow volatile chemicals to come into contact with the casing or
operation panel. Also, do not allow the instrument to come into contact with
any rubber or vinyl products for prolonged periods. Since the operation panel
is made of thermoplastic resin, be careful not to let it come into contact with
any heat sources such as a soldering iron.
●Before cleaning the case and operation panel, make sure that the power cord
is unplugged from the outlet if you are using an AC adapter. Dampen a clean
soft cloth with water and gently wipe the surface of the casing and panel.
Water getting inside the instrument may result in a failure.
●If the AC adapter will not be used for a prolonged period, unplug the power
cord from the outlet.
●For precautions on handling dry batteries, refer to "3.2.1 Using Alkaline
Batteries."
●Do not use the instrument with the cover for the battery holder left open.

Before Starting Source or Measurement
Safety Precautions
●Before using the instrument, be sure to thoroughly read "Safety Precautions"
on pages 4 and 5.
●Do not remove the casing from the instrument.
Some parts inside the instrument are extremely dangerous because they use
a high voltage. When the instrument needs an internal inspection or
calibration, contact Yokogawa Meters & Instruments Corporation or the
dealer from whom you purchased the instrument.
●In the case of an abnormality
If the instrument begins to emit smoke, give off an unusual odor, or show any
other signs of an abnormality, immediately turn off the power switch. If you are
using an AC adapter, unplug the power cord from the outlet. Also turn off any
object under test that is connected to the input terminals.
● AC adapter and power cord
Use the designated AC adapter. Do not place anything on the AC adapter or
power cord, and prevent heat sources from coming into contact with them.
When unplugging the power cord from the outlet, be sure to hold the plug and
never pull the actual cord. If the power cord is damaged, contact your dealer.

4.4 Source Resistance () Signals
4.4 Source Resistance () Signals
Procedure for Generating Resistance Signals
• The instrument generates a resistance signal by receiving the resistancemeasuring current I supplied from the device under calibration (resistance
meter, RTD thermometer, etc.) and delivering the voltage V = R I
proportional to the preset resistance R between the output terminals, and
thus producing the equivalent resistance R = V/I.
Consequently, the instrument generates the signal correctly only for such
devices that employ this method of measurement.
• The allowable range of the resistance measuring current I that the instrument
receives from a resistance measuring device under calibration is rated as
0.01 to 5 mA. (This varies depending on the generated resistance value. For
details, refer to the specifications.)
Obtaining Accurate Measurements
• Since the generated resistance value is calibrated without including the
voltage drop component of the lead cables, the resistance (approximately 0.1
on a round-trip basis) of the lead cables becomes an error in the case of a
load current.
• For accurate generation of resistance signals, use a three-wire connection for
output. (Refer to the figure below.)
• If the capacitance between the terminals of a device under calibration is
greater than 0.01 F, the instrument may be unable to generate correct
resistance values.

Measurement
• Turn off the power supply to the object to be tested before connecting it to the
instrument. It is extremely dangerous to connect and disconnect measurement lead cables while power is being supplied to the object.
• It is extremely dangerous to incorrectly connect the voltage input terminal H
and the current input terminal mA. Make sure that the measurement function
(FUNCTION) selection and terminal connections are correct. An incorrect connection may not only cause damage to the circuit or device under test and the
instrument, but also result in injury to the operator.
• The maximum allowable applied voltage for the grounding of all input/output
terminals is 42 Vpeak. Be sure not to exceed this voltage because doing so
may not only cause damage to the instrument, but also result in injury to the
operator.

● About Resistance (500 ) Internal Offset Calibration
*: When performing zero point calibration, make sure the voltage between the
H and L terminals is within approximately 20 V (0.02 mV). If this value is
exceeded, the instrument needs to be repaired (internal calibration).
● About Resistance Excitation Current
When calibrating the 500 and 5 k ranges, two types of calibration are
required because of differences of current (excitation current) inflowing from
an external device.

9.1 Calibration of Source Functions (Adjustment)
Tip
• You can select to calibrate just the functions and ranges that require calibration. (Be
sure to perform both zero point and full scale (FS) calibration of the same range
together.)
• Calibration of thermocouple (TC) and resistance temperature detector (RTD) takes
place at the same time as calibration of the100 mV and 500 ranges.

Appendix 1 Using a Cold Junction
Compensator
Standard thermocouple tables give 0C as the temperature of the reference
junction. Normally, the input terminal part (reference junction) of a thermometer
(device under calibration) is at room temperature. (This results in an error
equivalent to the difference between 0C and room temperature.)
Cold junction compensation involves measuring (detecting) the temperature of
the reference junction, calculating the temperature difference (thermoelectric
power difference) from 0C, and then carrying out compensation based on the
result.
Use an external RJ sensor (or the built-in RJ sensor) for measuring (detecting)
the temperature of the reference junction.
A cold junction compensator can be used when, for example, it is not possible to
use an RJ sensor. The use of a cold junction compensator enables the
reference junction to be 0C.
