M830B MULTI METERThis seriesmeter is designed to measure temperature with "K" type thermocouple,each module of thermocouple has it's measuring range, for example, HYTP083010is suitable for temperature of -20oC to 250oC and themeasurement range of HYTP083104 is -20oC to 750oCFeaturesMaximumvoltage betweenTerminalsand earth ground : CAT II 600VFuseprotection : F 250mA/250VPower Supply : 9V battery, NEDA1604 or 6F22Display : LCD 1999 counts, updates 2-3/secMeasuring method : Dual -slope integration A/D converter Over rangeindication : Only figure "1" on thedisplayPolarityindication : "-" displayed for negativepolarity Operatingtemperature : 0OC to 40oC ( 32oFto 104oF)Storagetemperature : -10oC to 50oC (10oFto 122oF)Low batteryindication : "BAT" appears on the display Size : 126 x70x25mmWight : Approx. 170gCAUTIONUsing thisappliance in an environment with a strong radiated radio-frequencyelectromagnetic field(approximately 3V/m), may influence its measuringaccuracy. The measuring result can be strongly deviating from the actual value.
