Performing the Zero Adjustment
3.5 Performing the Zero Adjustment
Remove the residual components due to offset and the measurement environment.
Be sure to perform the zero adjustment before the impedance measurement and the voltage
measurement.
Performing the zero adjustment
Placing the measurement probe (Example: L2002)
Place the measurement probe in the same condition as the measurement is performed.

The zero residual volume differs due to the condition of the measurement probe (length, shape, and location).
Thus, place the measurement probe in the same condition as the actual measurement is performed, before
performing the zero adjustment.
Prepare the zero adjustment board (accessory).

the frequency. The lower the frequency, the longer it takes to set (Reference:
approx. 350 s for 0.1 Hz, approx. 45 s for 1 Hz).
When setting at a different range and/or frequency, zero adjustment will be
invalid.
The zero adjustments for the range that is presently set, and the full range
of the frequency, and the voltage measurement are performed. Even if the
measurement frequency is changed, the zero adjustment is effective. However,
when the range is changed, the zero adjustment is not effective.
26
• When the zero adjustment is effective, the indicator of 0 ADJ appears on the measurement
screen.
• After performing the zero adjustment, even if the zero adjustment becomes ineffective, the zero

Impedance measurement error due to voltage drift (Indication: VOLTAGE DRIFT)
The voltage of the measuring object considerably uctuates during the measurement.
When the difference between voltage values at the start and at the end of measurement is 10 mV
or more, the difference is detected as an error.
The probe’s return cable is not properly connected. It may be disconnected or the wire connection
may be wrong.
To reduce noise due to the electromagnetic induction, it needs the return cable where the current
ows opposed to the measurement current. The return cable has a structure that short-circuits
between the shield wire of the SOURCE-H and the shield wire of the SOURCE-L. (In the optional
probe, the return cable short-circuits between the shield wire of the SOURCE-H and the shield wire
of the SOURCE-L.)

Maintaining Voltage Measurement Accuracy (Self-Calibration Function)
4.3 Maintaining Voltage Measurement Accuracy
(Self-Calibration Function)
This function compensates the offset voltage and the gain drift in the internal part of the circuit, to
improve the voltage measurement accuracy.
To satisfy the instrument’s measurement accuracy, the self-calibration is required. Be sure to
perform it. Be sure to perform the self-calibration especially after warming-up or when the ambient
temperature has changed more than 2°C.
The methods for conguring self-calibration to run are as follows:
Self calibration of 0.2 s is automatically executed before measuring the voltage.

External Control (EXT.I/O)
Using the EXT.I/O terminals on the rear of the instrument, the instrument can be controlled by
external devices such as PLC.
The instrument can also be controlled by outputting the measurement ending signal and the judgment result
signal, and by inputting the measurement starting signal by using the EXT.I/O connector on the rear. All of the
signals are isolated from the measurement circuit and the ground. (The common terminals for input and output
are shared.) The input circuit can be switched so as to correspond to the current sink output (NPN) or the
current source output (PNP).
To use the instrument properly, conrm input/output ratings and the internal circuit conguration, and
understand the safety precautions before connecting to a control system.
Signal input/output
Check the specications of the controller’s input/output.
Set the NPN/PNP switches of the instrument (p. 80).
Connect between the EXT.I/O connector of the instrument and the controller (p. 80).
Congure the instrument settings.

External Input/output Terminals and Signals
Functions of each signal
Input signal
START (TRIG)When START (TRIG) signal is switched from OFF to ON, measurement is performed
once on the edge.
This is only effective when TRIGGER SOURCE is set to the external [EXT] side.
0ADJ_ALLWhen the 0ADJ_ALL signal is switched from OFF to ON, all zero adjustment (p. 26)
is performed once on the edge.
STOPWhen the STOP signal is switched from OFF to ON, the measurement is interrupted
on the edge.
0ADJ_SPOTWhen the 0ADJ_ALL signal is switched from OFF to ON, spot zero adjustment
(p. 26) is performed on the edge.
CALWhen the CAL signal is switched from OFF to ON in the self-calibration manual
setting, the self-calibration is started on the edge. When self-calibration is set to auto,
the above is ineffective.
Self-calibration takes approximately 210 ms. When a switch is input during
measurement, self-calibration is performed after the measurement.
LOAD0 to LOAD6When the number of the panel to load is selected and the TRIG signal is input, the
selected panel number is read and measured. LOAD0 is LSB and LOAD6 is MSB.
When the TRIG signal is input, if LOAD0 to LOAD6 are the same as the previous
ones, the panel load is not performed. In the above case, when the external trigger
is used, the measurement is performed once as a normal TRIG signal. When the
internal trigger is used, the input of LOAD0 to LOAD6 is ineffective.

• In the case of setting to the external trigger, the measurement is performed once
after the completion of the loading.
• In the case of setting to the internal trigger, panel loading will not be performed.

External Input/output Terminals and Signals
Output signal
ERRWhen a measurement error (p. 30) occurs, the output changes to ON. (In the
case of the overrange, the output is OFF.) ERR is updated just before the EOM
signal.
When ERR is ON, all of the comparator judgment outputs become OFF.
In the case of a measurement error: ERR output changes to ON
In the case of a normal measurement: ERR output changes to OFF
PASSWhen the results of the measurement parameters being judged are all IN, the
PASS is ON.
Example 1: When the functions (R, X, V, T) are set, if all of the measurement
results of R, X, V are IN, the PASS is ON.
Example 2: When the functions (V, T) are set, if the measurement result of V is IN,
the PASS is ON.
EOMEOM is end of measurement. When EOM changes to ON, the judgment result of
the comparator and the ERR output have been determined.
INDEXINDEX indicates that the A/D conversion has ended in the measurement circuit.
When the signal changes from OFF to ON, the object being measured can be
removed from the probe.
FAILIt will be ON when the judgment results of comparator are Hi or Lo.
RorZ_HIThe RorZ_HI is the judgment result of the comparator for resistance or impedance.
RorZ_IN, RorZ_LOThe RorZ_IN and RorZ_LO are the judgment results of the comparator for
resistance or impedance.
V_HI, V_IN, V_LOThey are the judgment results of the comparator for voltage.
Xor
HI, Xorθ_IN,
Xor
θ_

LO
They are the judgment results of the comparator for reactant or a phase angle.
IMPORTANT
• The I/O signals cannot be used during changing the measurement conditions in the instrument.
• When the power supply is turned on, the EOM signal and the INDEX signal are initialized to
ON.
• When it is not necessary to switch the measurement conditions, x all of LOAD0 to LOAD6 at
ON or OFF.
• To avoid misjudgment, check with both the PASS and FAIL signals for the judgment to the
comparator.

• Do not input TRIG signal when measurement (INDEX signal is OFF) is in progress.
• When settings such as measurement frequency are changed, input the TRIG signal after the

• The input signal is disabled when the measurement screen is not open, or when an error
message is displayed.
• The output of the judgment result is determined before the EOM signal becomes ON. When
