Page 5: Introduction
INTRODUCTION The Interscan GF1900 Sulfuryl Fluoride gas fumigant analyzer is expressly designed for use as a clearance monitoring device to determine safe re-occupation of a structure after aeration only. Use of this device for any purposes other than use as a clearance device will invalidate the warranty. - Page 6 Ready L.E.D. - illuminates when furnace reaches proper preset operating temperature. NOTE: The “Ready” L.E.D. is not an indicator of Sensor stabilization. LO BAT. – illuminates when battery pack or AC power supply is at or below 19.0 V DC. Meter –...
- Page 7 Gas sample inlet PORT. Tubing is pushed into port until seated and then gently pulling back. The pulling back action is performed to properly seal the connection. Teflon tubing ¼ O.D. x 1/8 I.D. is recommended for use. Length should not exceed twelve (12) inches when used with factory calibration.

Page 8: Cautions
CAUTIONS Items inside yellow boundary can cause injury. Do not attempt to service until instrument has cooled for one (1) hour. DO NOT attempt to use in areas where gasoline, sulfur compounds, or highly flammable vapors are present. The presence of any of these could produce an EXPLOSION. -
Page 9: Operation
OPERATION 1) Turn the FUNCTION SWITCH knob to the OFF position and connect an AC power supply or battery pack. Tighten the connector completely. NOTE: Turn only the knurled ring to tighten. Tightening the connection by turning any other portion of cable can result in a short, fire, or explosion. 2) Turn the FUNCTION SWITCH to ON or BAT TEST and wait for the READY indicator to light. -
Page 10: Calibration
CALIBRATION Note: Should be done every 3 months or more frequent. Some companies require monthly calibration. The instrument is calibrated by introducing, a known concentration of Sulfuryl Fluoride gas (5 ppm), and adjusting the SPAN control to correspond to the known analysis of the gas. -
Page 11: Maintenance
MAINTENANCE Furnace Replacement Make sure power is disconnected and the analyzer is allowed to cool. Do not attempt to service until cooled for a minimum of one (1) hour. Remove the thermocouple leads at terminals 3 and 6 of the terminal block. For easy access, loosen the sensor clamp screw and lift the sensor out, placing it on the fan. -
Page 12: Trouble Shooting
TROUBLE SHOOTING READY light does not illuminate. Check that the POWER L.E.D. is illuminated. If it is not: 1) Check the main fuse. 2) Check that the rear connector is tight. 3) Check the power source for a nominal 24V. 4) Check that the circuit board connector is tight. - Page 13 Furnace is hot, READY light is not on. Thermocouple may be defective. Check across leads for mV reading. The reading should be greater than 20 mV after 5 minutes. Reverse thermocouple leads if the reading is negative. If thermocouple is okay, R27 may be set incorrectly. With the thermocouple reading approximately 35 mV, adjust R27 to get a READY indication.
