Circuit System

1) Direct-acting - Input signal is applied directly to the coil.
2) Electronic - Direct current amplification is performed forthe input signal of the DC voltmeter and internal
resistance is increased (DC voltmeter only).

Features● Comparative measurements for measurement control ofseries such as directed standard values and measurement
values can be conducted with ease because the DEF - 15W
and DEF - 17W are integrated in a pair meter structure.
● Optimal for system display panels and graphic monitoring
panels. Appropriate for areas with dense instrumentation asvery little space is required for installation.
● Two or more units can be neatly connected.
● Tag plates are attached to the top and bottom to display
information such as measuring point name and tag number.
● The scale is brighter, larger and easier to read, making it easy
to perform a series of control operations.
● Parts such as the zero-point adjuster and the scale plate canbe replaced because the meter unit can be easily removed
from the front side.

7mm.
At this point the clamping mechanism is released.
The name plate will not come out any further, but be careful because the meter unit may pop
out if it is facing downward.

2. The meter unit can be completely removed, but the last part has astopper on it, so remove the unit by pulling up and towards yourself.

4. Insert the connector followed by the main unit to install the meter
unit. After pushing in the meter unit part-way, push in the nameplate, then push in the meter unit the rest of the way until you hear
it lock into place with a click.
The name plate and meter unit can be pushed into place in any order, but make sure
afterwards that the meter unit does not come out when pulled on.

1. Hook your finger on the bottom part of the name plate and pull it out.

First the name plate comes out, then the meter unit comes out until it protrudes by approx. 7mm.
At this point the clamping mechanism is released.
The name plate will not come out any further, but be careful because the meter unit may
pop out if it is facing downward.

3. After adjusting zero-point, push in the meter unit part-way, pushin the name plate, then push in the meter unit the rest of theway until you hear it lock into place with a click.
The name plate and meter unit can be pushed into place in any order, but make sure
afterwards that the meter unit does not come out when pulled on.

2. Adjust zero-point after pulling the meter unit out into a position
where the adjustment can be carried out.

Adjust zero-point on the side face by turning the circular plate printed with [ZERO ADJ]. Thisis on the same side as the [] symbols in the same color as the pointer. Turn the plateusing a screwdriver that fits inside the groove properly. Using an inappropriate size may
break the groove.

[Replacing the Name Plate][Replacing the Scale Plate]

1. The upper name plate can be removed by hooking your finger
around the upper part and pulling towards you.
2. The lower name plate can be removed by hooking your finger
around the lower part and pulling it out, then pushing an object
such as a screwdriver into the tab on the side and pulling out andtowards you. It can be easily removed by simply pulling out one of
the tabs.
3. Both the upper and lower nameplates can be attached by pushingthem in.

1. Pull the meter unit out from the meter frame.
2. Take out the two screws and remove the cover.
3. Take out the two screws and replace the scale plate cassette.
4. Do not touch the pointer when attaching the cassette or cover.

[For the EF-15W]① Scale Plate

1. Insert the meter from the front
side of the panel.
2. Use the attachment brackets to
fix the top and bottom of themeter in place from the back.

1. If the ammeters exceeds 5 A, the product has a 60mV meter with an externallyattached shunt.
2. If the voltmeter exceeds 500V, an externally attached series resistor is included.
(Except for the DEf-100ND meter, which has an externally attached series resistor
when exceeding 150V.)
3. Internal resistance of zero-center meters(a) The value for voltmeters is the same as for zero-left meters.
(b) The sum maximum value for ammeters is the same as for the corresponding
zero-left meter.
4. Shunts and series resistors can be externally attached upon request, even for therange of input signals on the left.
5. Tolerance for all internal resistance values is within ±30%.

1. The meter which has an input signal of 1-5V with a resistance of 1MΩ comes with anamplifier and requires a DC24V auxiliary power supply.
2. Current consumption is 20mA for one circuit (40mA for two circuits).
3. Specify the input signal and internal resistance value as an input signal of 1 - 5V witha resistance of 25kΩ is optional.

Be sure to check the zero-point of the pointer before passing an electric
current through the meter.
If the pointer is deviating, adjust it using the following procedure.
(1) For meters with a value from 0 to maximum, adjust the zero-point
adjuster on the front by using a 3 to 3.6mm flat-head screwdriver torotate the pointer left or right.
(2) For meters without a 0 scale (expanded scale meters), such as the
4 - 20mA meter, apply electricity equivalent to the minimum scalevalue and adjust the zero-point adjuster by rotating the pointer left or
right with a screwdriver to match the minimum scale value.

as listed in the table.

Horizontal Type (Y)(2) Rotating to the right when adjusting will increase the pointerindication, while rotating left will decrease it. The adjustable range isapproximately 5% or more of the maximum scale value.
(3) If an error is discovered, adjusting the maximum value with thezero-point adjuster will break down the linearity of the scale andresult in overall error. In such cases, thoroughly investigate the source

1of the error and request repairs or replacement if the meter is the3cause.
