Beschreibung:
Der CEM AT-9955 ist ein universales Messgerät mit sondern Funktionen für die Prüfung- und Reparaturarbeit an Fahrzeuge. Neben die Standarden Messfunktionen für Strom AC/DC, Spannung AC/DC, Widerstand, Frequenz, Temperatur, Kapazität, Kontinuität, Dioden-Prüfung und Tastverhältnis (Duty Cycle) kann er noch RPM (Drehzahl), Schließwinkel und Impulse messen. Das Messgerät misst die Pulsbreite in Millisekunden (ms) damit kann er On-Time von Einspritzdüsen, Leerlaufluftstellmotoren, elektronischen Getriebesteuerungen, usw. viel besser überprüfen. Zur Temperaturmessung steht ein Typ-K Kontaktfühler sowie auch ein Infrarot-Temperatursensor (Optik 8:1, -30°C bis 550°C) zur Verfügung.
Features:
- Revolutions Per Minute (RPM) measurement for automotive engines with 4 to 8 Cylinders using the inductive pick-up
- 4000 counts LCD display with backlight
- 14 functions including RPM (Tach), Dwell Angle, pulse, DCV, ACV, DCA, ACA, Resistance, Duty Cycle, Frequency, Temperature (Type-K / IR), Capacitance, Continuity and Diode Check
- Read pulse duty cycle and dwell angle for electronic fuel injection feedback carburetors and ignition
- Peak, Max. / Min. Detection
- Over-range indication
- Auto Power Off
- HOLD function
- Fused current inputs and Overload protection on all ranges
- Measuring the pulse width in milliseconds (ms)
- CAT III 1000V
