THERMOCOUPLE SOURCE SERIES 22 - ALTEK …

1 DATA SHEET 22 Additional THERMOCOUPLE Calibrators: See Data Sheets 222A, 322 & 422 GENERAL DESCRIPTIONALTEKTHERMOCOUPLE SOURCESERIES 22 ALTEK SERIES 22 THERMOCOUPLE Sources provide22 precise temperatures for inputs to transmitters,recorders, controllers, alarms, data acquisition andcomputer systems. Model 22 provides thermocouplewire output and is cold-junction compensated forambient temperature variations. Conformity to theparticular THERMOCOUPLE vs millivolt curve is inaccordance with the latest ASTM and IPTS standards for exact temperature simulation. Linearmillivolt models are also types B, E, J, K, R, S and T areavailable in both degrees F and C. The table liststhe standard ranges. Resolution is 25, 50 or 100degrees, corresponding to full scale output of 500,1000, 1700, 2100 and 3100 degrees ranges, with an individual ON position foreach range, allow quick, easy settings for anyoutput.

2 Calibrated accuracy is of span 1degree. Negative temperatures add 2 built-in AA cells provide power for one year ofeveryday use. A front panel LED pulses every timethe Model 22 is turned on to indicate proper low cost ALTEK MODEL 22 is a complete,compact SOURCE for checkout and calibration of allthermocouple instruments in the field, shop orcontrol INSTRUCTIONSS elect the ALTEK MODEL 22 for the correctthermocouple type, the desired temperature scale (F or C), and the ALTEK THERMOCOUPLE SOURCE to the input terminals of the instrument to be tested, the field mounted head or junction box compensation and instantaneousautomatic standardization is built into the Model the temperature selection switch to the desiredtemperature and slide the ON switch to the selectedscale.

3 The Battery Check LED will pulse once indicatingproper battery voltage. If no pulse is seen, the batteriesshould be replaced with 2 AA cells. Alkaline cells are preferred for longest life and widest operatingtemperature point calibration temperatures of the instrument are then selected on the Model 22 and any requiredadjustments are made. Intermediate points may then be selected to verify instrument linearity or check critical equipment is guaranteed against defective materialand workmanship (excluding batteries) for a period ofthree years from date of shipment. Claims underguarantee can be made by returning the equipmentprepaid to our factory. The equipment will be replaced,repaired or adjusted at our option. The liability of ALTEK isrestricted to that given under our guarantee.
