8. FIVE-INCH CHARTS ARE
ECONOMICAL A 50% savings in paper can mean hundreds or thousands of dollars in the life of a recorder. Five-inch charts are handier too for notebooks, reports orfiles. And in round-the-table conferences, smaller charts can be set side by side, giving more data and less clutter.
1 & 2 channel versions use same 5-inch chart paper; 1% limit of error and 1 or2Sâ secondfull-scale balancing time; chart speeds from Jg inch per hour to 16 in./min.; prices from $365; numerous options described in Varian literature. Write the Instrument Division.
