Set the decade box to the resistance value corresponding to the lower temperature. Adjust the Zero pot until the milliammeter reads 4.0 mA +/- 0.016 mA. - Page 6 37°F (OFF, ON, OFF and ON) which is the next higher range. Likewise if the Span trim pot does not have sufficient adjustment, then the Span switch settings should be changed. Minco Tel: 763. 571.3121 • Fax: 763. 571.0927 • www.minco.com...
