Introduction
Illustration 1.The 9U-7401 Multitach II is a hand-held battery operated, dual channel digital tachometer. It replaces the former 6V-2100 Multitach with a much more versatile unit. Multitach II is actually three instruments in one, a Programmable Tachometer, an Engine Set Point Indicator, and a Frequency Meter. The following features are included in Multitach II: * Rechargeable, battery-operated.* Two digital displays show Input 1 and Input 2 values simultaneously.* Engine set point indicator captures and displays set point RPM.* Hz frequency meter measures gen set or other signal frequency.* Non-volatile memory allows storage of all values on display.* Displays minimum, maximum, and difference values of inputs.* Displays difference between Input 1 and Input 2.* Display backlight for operation in low-light conditions. * Optional RS232 output available for printing directly to printer.Multitach II accepts many different types of pickups including most pickups used with the former Multitach II. Each input can be programmed separately with different PPR (Pulses Per Revolution) values for each input. Also, a different type of pickup can be used on each input at the same time. Operation is easy because Multitach II always stays preprogrammed for the values it was last used with. It is ready to display values when turned ON.Contents of 9U-7400 Multitach II Group

Refer to statement before using alkaline batteries.
If the nickel cadmium rechargeable batteries are removed and alkaline batteries are installed, do not attempt to recharge or damage to the indicator may result. If alkaline batteries are installed, place tape over the charge connector to prevent accidental charging.
Use the following graph to determine accuracy for any PPR and RPM combination. Use smallest PPR number possible for highest accuracy.

Illustration 6. Digital Display.1. INPUT 1 DIGITAL DISPLAY: Displays the values for Input 1 functions.2. MAX and MAX - MIN Indicator: MAX only will show when the maximum value is being shown. MAX - MIN will show when the difference value (maximum value minus minimum value) is on the display.3. INPUT 1: Indicates this upper display shows Input 1 values, also flashes after INPUT 1 key has been pressed to indicate that all keys will work for Input 1 when flashing.4. LO BAT: Shows on display only when the internal NiCad Batteries need recharging. See the "Charging the Internal Nickel Cadmium Batteries" section in this manual, to check battery Voltage.
If the nickel cadmium rechargeable batteries are removed and alkaline batteries are installed, do not attempt to recharge or damage to the indicator may result. If alkaline batteries are installed, place tape over the charge connector to prevent accidental charging.
