Specifications
Accuracy: All DC and AC iron-vane; ±2%
of full-scale AC rectifie r type; ±3% of
full scale (with 60 Hz sine wave at 25º C).
When standard 60 Hz iron vane ammeters
are used at the extreme limits of 25 or 400
Hz, additional error (approx. .75%) may be
experience d. Expanded-scale voltmeters:
±.5% of full scale value.
ANSI Specif ica tion: All meters meet ANSI
Specifications C- 39.1
Overload: Voltmete rs (AC and DC) - 50%
momentary, 20% sustained. Ammeters
(AC and DC) mome ntary; 10 time s the
rate d cur rent for 10 consecutive intervals
of .5 second with a 1 minute interval
between successive applications; sustained:
20% for six hours.
Scale Dat a: 90 degree rotation.

How To Order
To order New Big Look panel meters use
the appropriate catalog numbers provided
in the tables. Taut band & AC I/V instruments
have a 250 prefix number. Pivot & Jewel instru-
ments have a prefix of 254.
Ordering Examples:
1. 21⁄2”, 300 V DC Voltmeter, zero lef t, taut
band - 250 220 RXRX
2. 21⁄2”, 300 V DC Voltmeter, zero lef t,
pivot & jewel, 254 style - 254 220 RXRX
3. 21⁄2”, 300 V AC (Iron Vane), pivot &
jewel - 250244 RXRX
Notes:
Pivot & jewel instruments are not available in
11⁄2” size.
Severe-duty mete rs are available to meet CSA,
UL 1437 and IEC 144 requirements. UL/CSA
version, w ith flame retardant window and
base, is not offered in 11⁄2”. IEC version is
not offered in 1 1⁄2” and 41⁄2”. To order, add /CSA,
/UL or IEC af ter catalog number, o r contact
factory.

Specifications
Accuracy: All DC and AC iron-vane; ±2%
of full-scale, AC rectifie r type; ±3%
of full scale (with 60 Hz sine wave at 25º C).
When standard 60 Hz iron vane ammeters
are used at the extreme limits of 20 or 400
Hz, additional error (approx. .75%) may be
experience d. Expanded-scale voltmeters;
±.5% of full scale value.
ANSI Specif ica tion: All meters meet ANSI
Specifications C- 39.1.
Overload: Voltmeters (AC and DC) - 50%
momentary, 20% sustained. Ammeters
(AC and DC) mome ntary: 10 time s the
rate d cur rent for 10 consecutive intervals
of .5 second with a 1 minute interval
between successive applications; sustained:
20% for six hours.
Scale Dat a: 90 degree rotation.

and 2.5 seconds (max.) for AC ratings.
Maximum of 40% overshoot.
Dimensions: Se e page 34- 35.
How To Order
To Order Horizon Line panel meters use
the appropriate catalog numbers provided
in the tables. Taut band instruments have
a 251 prefix number, Pivot & jewel instruments
have a 255 prefix number, except AC Iron Vane
prefix which is 251.
Ordering Examples:
1. 21⁄2”, 300 V DC Voltmeter, zero lef t, taut
band - 251 220 RXRX
2. 21⁄2”, 300 V DC Voltmeter, zero lef t,
pivot & jewel - 255 220 RXRX
3. 21⁄2”, 300 VAC (Iron Vane) pivot & jewel -
251 244 RXRX
Severe-duty mete rs are available to meet UL
1437 requirements. UL/CSA version, with
flame retardant window and base, is not
of fered in 11⁄2”. To order, add /UL or /CSA
af ter catalog number, or contact factory. Fo r
ratings and scales not listed contact factory.
