• This product generates high voltage. Be careful of electric shock and electric discharge.
• To prevent electric shock, remove rings, watches, and other metallic accessories and
jewelry before operation.
Connect Cables Correctly
This instrument can generate large voltage and current. If you do not connect the devices
correctly, not only will it damage the instrument or the target device, it may also lead to electric
shock or fire. Be careful when you connect the cables, and be sure to check the following
points.
Before output (before turning on the output), check that:
• Cables have been connected to the instrument’s output terminals correctly.
Check that there are no voltage output cables that have been connected to the current
terminals.
Check that there are no current output cables that have been connected to the voltage
terminals.
• Cables have been connected to the target device correctly.
Check that there are no short circuits between voltage terminals or between the cables
connected to the voltage terminals.
• The cables are connected firmly to the current terminals.
• There no problems with the current terminals and the crimping terminals, such as the
presence of foreign substances.
During output (never touch the terminals or the connected cables when this instrument is on),
check that:
• There no problems with the current terminals and the crimping terminals, such as the
presence of foreign substances.
• The current terminals are not abnormally hot.
• The cables are connected firmly to the current terminals.
The terminal connections may become loose over time. If this happens, heat may be
generated due to changes in contact resistance. If you are going to take measurements
using the same setup for a long time, periodically check that the cables are firmly
connected to the terminals. Be sure to turn off both this instrument and the target device
before you check the connections.
After output (immediately after the output is turned off)
After you output a voltage or current, voltage may remain for some time even after you turn
the output off. This residual voltage may lead to electric shock. Do not touch the terminals
immediately after you turn the output off. The amount of time that voltage remains varies
depending on the target device.

2.2 Output
Turning the Output On and Off
There are two output modes: OFF and ON.
OFF: The output is disconnected. The specified output level is not generated.
ON: The output is connected, and the specified output level is generated. During output, the output
display shows the voltage or current.
Frequency and Phase Angle
Fixed Frequency (50 Hz, 60 Hz, or 400 Hz)
The 2558A uses its internal oscillator to output sinusoidal voltage or current. 50 Hz and 60 Hz are
used for devices that receive power line signals. 400 Hz is mainly used for meters used in aircrafts
and marine vessels.
Specific Frequency (VAR)
The 2558A uses its internal variable oscillator to output sinusoidal voltage or current. You can
specify a frequency of your choice using a dial on the front panel. The setting is shown on the front
panel. The accuracy is the same if you set one of the fixed frequencies with this feature.
Selectable range: 40 Hz to 1000 Hz
External Oscillator EXT1
To output voltage or current, connect an external oscillator to the I side (EXT1) of the 2558A’s
external signal input terminal. Use this feature when you need to synchronize with other signals
(i.e., function generator). The phase between input and output is reversed in order to accommodate
compatibility with the predecessor model, 2558. The 2558A measures the external oscillator
frequency and shows it on the front panel.
Input range: 40 Hz to 1000 Hz
2
Features
External Oscillator EXT2 (PHASE)
To output voltage or current, connect the two signal outputs from another 2558A. Use this feature to
perform synchronous operation between multiple 2558As. You can set the phase angle according to
the measurement system. The setting is shown on the front panel.
Selectable range: –180.000° to +359.999°
Input range: 40 Hz to 1000 Hz. The frequency is not shown on the front panel.

2.3 Output Divider
Main setting = 10 A
n = 0
m = 4
Ammeter
When calibrating the target meter, the output divider feature divides the voltage or current level or the
frequency into as many points as you need to calibrate. You can set the main setting to the maximum
indication on the target meter, and vary the divider value to calibrate the various points on the meter.
Divider value range: n/m where n = 0 to m and m = 4 to 15
Setup example: When the main setting is 10 A, n is 2, and m is 4,
output value = 10 A×2/4 = 5 A (divider value: 1/2)
Ammeter
0 A
Frequency Output Divider
If the frequency is set to FREQUENCY METER MIN or FREQUENCY METER MAX, the oscillation
frequency is divided and output. The main setting is not divided.
For example, if the MIN frequency is 45 Hz, the MAX frequency is 65 Hz, and the main setting is 100 V,
the following result is obtained.
At n =0 and m = 4, the output voltage is 100 V, and the frequency meter shows 45 Hz.
At n =2 and m = 4, the output voltage is 100 V, and the frequency meter shows 55Hz.
At n =4 and m = 4, the output voltage is 100 V, and the frequency meter shows 65Hz.
In this example, the frequency width of 20 Hz is divided into four parts and output at 5 Hz intervals.
The voltage level is not divided.

2.4 Deviation and Presets
Main setting = 10 A
Error (deviation)
Use the deviation dial to align
the meter needle to the accurate
scale position.
The deviation is –0.30%.
Deviation
This feature is used to check the relative error (deviation) of the meter scale calibration. If the meter
needle is not pointing accurately to the appropriate scale mark, you can turn a deviation dial on the
front panel to finely adjust the voltage or current output level or the frequency so that the needle points
accurately to the mark. The amount of fine adjustment is displayed as the deviation.
Deviation setting range: ±20.00%
Setup example: Main setting = 10 A, divider value n/m = 1
2
Features
Ammeter
9.97 A
Ammeter
10 A
In the example above, before fine adjustment, the meter needle is pointing to 9.97 A, which is 0.30%
smaller than the 10 A current output from the 2558A. The deviation polarity (the sign) of the 2558A
indicates whether the target device indication is larger or smaller than the accurate position. In this
example, because the meter is pointing to a value that is 0.30% smaller than the 2558A output value,
the 2558A displays –0.30%.
Deviation at Each Calibration Point
When the deviation feature is used in conjunction with the output divider feature explained in section
2.3, you can check at each calibration point the deviation in reference to the maximum scale value.
Note that if the frequency is set to FREQUENCY METER MIN or FREQUENCY METER MAX, the
deviation is in reference to the span.
When the maximum scale value is 10 A, 1% is 0.1 A.
If you are using the output divider feature at n = 2 and m = 10, when 2 A is being output, 1% will
also be 0.1 A.

short of the calibration point
Example when calibrating
in increasing order
2.4 Deviation and Presets
Presets
Deviation presets can be used to make the meter indicate values that are short of the accurate scale
positions when you change the output divider setting.
You can use this feature to calibrate a meter when using the output divider feature to calibrate the
points in increasing or decreasing order.
5%: When calibrating in increasing order, the deviation is set to +5.00%.
When calibrating in decreasing order, the deviation is set to –5.00%.
2%: When calibrating in increasing order, the deviation is set to +2.00%.
When calibrating in decreasing order, the deviation is set to –2.00%.
0%: The deviation is cleared when the divider value is changed.
OFF: The specified deviation is retained even when the divider value is changed.
Main setting = 10 A
Preset (5%)
Indicates a point that is
by the preset amount
Ammeter
4.5 A
Use the n dial to move
the meter needle up.
Indicates a point that is
short of the calibration point
by the preset amount
Ammeter
9.5 A
In the above example, the 2558A is generating –5.00% of the output setting. To calibrate the scale,
turn a deviation dial to move the meter needle to the correct position. For details on how to read the
deviation, see “Deviation” on the previous page.
