How To Order
To order New Big Look panel meters use
the appropriate catalog numbers provide d
in the tables. Taut band & AC I/V instruments
have a 250 prefix number. Pivot & Jewel
instruments have a prefix of 254.
Ordering Examples:
1. 21⁄2", 300 V DC Voltmeter, zero left, taut
band - 250 220 RXRX
2. 21⁄2", 300 V DC Voltmeter, zero left,
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.
Meter wi th flame retardant window and base in
21⁄2", 31⁄2" and 41⁄2" sizes are available that
conform to UL1437. Include /CUL or /UL at the
end of the catalog number o r contact factory.
Sealed meters for outdo or use can be ordered
in 21⁄2", 31⁄2" and 41⁄2" sizes by including /IEC at
the end of the catalog number, or contact
factory.
For ratings and scales not listed contact the
factory.

Specifications
Accuracy: All DC and AC iron-vane; ±2%
of full-scale, AC rectifie r type; ±3%
of full scale (wi th 60 Hz sine wave at 25º C).
When standard 60 Hz iron vane ammete rs
are use d 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 me et ANSI

How To Order
To Order Hor izon Line panel meters use
the appropriate catalog numbers provide d
in the tables. Taut band instruments have
a 251 prefix number, Pivot & jewel instr uments
have a 255 prefix number, except AC Iron Vane
prefix which is 251.
Ordering Examples:
1. 21⁄2", 300 V DC Voltmeter, zero left, taut
band - 251 220 RXRX
2. 21⁄2", 300 V DC Voltmeter, zero left,
pivot & jewel - 255 220 RXRX
3. 21⁄2", 300 VAC (Iron Vane) pivot & jewel -
251 244 RXRX
Severe-duty meters a re available to meet UL
1437 requirements. UL version, with f lame
retardant window and base, is not offered in
11⁄2". To order, add /UL or /CUL after catalog
number, or contact factor y. Fo r ratings and
