Page 3: Equipment Description
Introduction Note: It is not necessary to calibrate the monitor when received from the Interscan or an authorized distributor. All Interscan monitors are calibrated at the factory prior to shipment. The Interscan 4000 Digital series operates on the principle of pulling a sample (Sample draw) through a sensor. - Page 4 Designation Function Indicates gas level when function switch is in LCD Display: ZERO or SAMPLE, and battery level when on BAT. TEST A or B. LED. Flashes ON/OFF when alarm set ALARM Light: point is exceeded. 25-Turn potentiometer with a screwdriver ALARM SET: adjustment.

You must allow 24 hours to stabilize prior to use if the batteries are replaced. 10-Turn Potentiometer. Allows the meter to ZERO: be adjusted to zero, by compensating for any background signal. -

Page 8: Operating Instructions
Operating Instructions For overseas shipment, analyzers are shipped with the 15-Pin D connector DISCONNECTED from the circuit board. This is to preserve the battery life during shipment. To re-connect the wire bundle, simply open the analyzer by removing the 2 screws located on the right side panel. - Page 9 Zeroing the Analyzer The Analyzer must always be zeroed, prior to use. Zero adjustments must be made in the SAMPLE mode, i.e. with the pump on, in air free of interfering gases. If necessary, use zero air or a C-12 filter (provided) to zero in the sampling area. When using C-12 zero filter, connect externally to gas inlet.
-
Page 10: Sampling
Sampling Analyzer must be zeroed prior to sampling (section 2.1). Set the FUNCTION switch to SAMPLE to activate the pump. If the INLET or OUTLET is blocked, the pump may stall. Note: Running the Analyzer with blocked INLET or OUTLET may lead to the sensor leaking caustic electrolyte leading to analyzer damage. -
Page 11: Calibration
Calibration Introduction All analyzers are factory calibrated prior to shipment. There is no easy answer as to how often a monitor should be calibrated. This is strictly a function of the application (gas concentration and frequency of exposure to target gas). The purpose for calibration is to compensate for any possible decrease in sensor sensitivity. - Page 12 As indicated on the certification sheet, the ECS program verifies sensor sensitivity only. It does not certify the analyzer as a whole. Most importantly, the ECS program is not a substitute for basic analyzer maintenance, nor does it check for malfunction of the analyzer components.

Page 13: Sample Bag & Pressurized Cylinder Calibration
Sample Bag Calibration & Pressurized Cylinder Calibration Whatever the source of calibration gas, the recommended method is to collect the gas in the proper sample bag, which is then attached to the analyzer INLET. The calibration gas is drawn from the proper sample bag through the sensor. -
Page 14: Calibration Procedure
Calibration Procedure Analyzer must be zeroed prior to calibration (sec 2.1). 1. For all gases, except Chlorine or other chemisorbable types, fill the 5 liter sample bag with calibration gas, and attach it to the external inlet fitting. This is best done by attaching a short length (2 inch) of 5/16 inch (7.9 mm) O.D. -
Page 15: General Maintenance
Battery Charging and Replacement All models of the 4000 Series analyzers use two “C” size alkaline batteries. These are located on the hinged door, right side (fig. 4 pg. 7). Polarity is marked on the door over the battery holder. -

indication difficult. It is recommended that the batteries be recharged if the reading in BATTERY TEST “A” is at 100 (ignoring the decimal place). Allowing the reading to drop below 100 is not recommended. Note: NiCd batteries can develop cell memory. - Page 17 distilled or deionized water into the sensor via the red plug, using the plastic syringe (provided). Refer to (fig. 7 pg. 16). Refillable sensors are identified by the red fill plug in the side of the sensor. The fill plug location may vary from (fig.
- Page 18 (fig. 9) Quick connect male elbow This is a quick connect system comprised of the body, o-ring and ferrule (fig. 9). Disconnect by pushing on the ring where the tubing enters the fitting and gently pulling on the tubing. Re-attach by inserting the tubing all the way in and then gently pull backward.
- Page 19 Fig. 11 For P-type sensors refer to (fig. 11). Disconnect the 2 electrical connections to the sensor. Disconnect the tubing from each gas fitting. Loosen the screw indicated as “A”. Loosen the clamp screw “B” until the sensor can be removed from clamp. NOTE: DO NOT REMOVE ANYTHING ELSE!!!!!! Restore the sensor to within 5 grams original sensor weight by injecting an equivalent cc of distilled or deionized water (10g.

Restore the sensor to within 5 grams original sensor weight by injecting an equivalent cc of distilled or deionized water (10g. weight loss means add 10cc water). DO NOT OVERFILL. If sensor will not take on any more liquid (liquid starts coming out the fill port) do not attempt to add additional distilled water. -

5.0 Troubleshooting No power. Ensure the FUNCTION switch is not in the OFF position. Symptom Corrective Action Are Ni-Cd batteries charged? (See Section 4.1) Pump won’t run. Ensure the FUNCTION switch is not in the OFF, or ZERO position. Are Ni-Cd batteries charged? (See Section 4.1) Are INLET/OUTLET fittings plugged? Is any tubing kinked? Can’t zero. -
Page 23: Warranty
Warranty INTERSCAN’s Warranty Policy INTERSCAN CORPORATION warrants portable analyzers of its manufacture (sensors, batteries, fuses, lamps, tubing, fittings, filters, and scrubbers excepted) to be free from defects in material and workmanship for a period of one year from date of shipment. -
Page 24: Return Authorization
Return Authorization INTERSCAN’s Return Authorization Policy All returns for repairs require a "RETURN AUTHORIZATION NUMBER" issued by the INTERSCAN Service Department upon request. This is done primarily to cause the user to contact the factory directly. The reason for this is that a high percentage of service problems are resolved over the telephone, avoiding the need for returning the analyzer or part. -

Refer to guidelines above covering isopropyl alcohol. Remember that you are attempting to monitor parts per million levels of ethylene oxide in an environment that may contain percent (10,000 ppm = 1 percent) levels of these potentially interfering compounds.
