How To Order
To Order Horizon Line panel meters use
the appropriate catalog numbers provide d
in the tables. Taut band instruments have
a 251 prefix number, Pivot & jewel instrume nts
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 meters a re available to meet UL
1437 requirements. UL version, wi th flame
retardant window and base, is not offered in
11⁄2". To order, add /UL or /CUL af ter catalog
number, or contact factor y. For ratings and
scales not liste d contact factor y.
