WARNING: If Error message 2, 3, 4, or 8 appears, the instrument must be sent to a
qualified organization for repair. See the Repair and Calibration section in the user
manual for return instructions.
BUTTON FUNCTIONS
Activates the secondary function of a button. The symbol appears on the
left side of the screen. Press this button and then press the desired button to
select the secondary function.
In SET-UP mode, selects a function or increments a ashing parameter.
In SET-UP mode, selects a function or decrements a ashing parameter.
In SET-UP mode, accesses the function to be modied.
In Wrap-Around mode, selects the parameter to be modied (from left to right).
In SET-UP mode, shifts the decimal point and selects the unit.
PRINT
Immediate printing of the measurement to a serial printer. If the temperature
compensation function has been activated, the calculated result and the
temperatures involved are also printed.
PRINT
MEM
Retrieves stored data for printing (this function is independent of the setting of
the switch) except in the OFF and SET-UP positions.
Activates or deactivates the temperature compensation function to calculate
the resistance measured at a temperature other than ambient measurement
temperature.
ALARM Activates or deactivates the alarms. High or low triggering values are adjusted
in SET-UP.
Selects the desired measurement mode prior to starting one of the following
measurements: Inductive mode (continuous test), non-inductive mode (instanta-
neous test) or non-inductive mode with automatic triggering (multiple tests).
METAL Selects the metal type for the temperature compensation calculation:
Cu, Al, or Other metal.
MEM
Stores the measurement at an address identied by an object number (OBJ)
and a test number (TEST).
Two presses on this button are required, one to select the location (use the ▲
and ► buttons to change the location) and another to store the measurement.
MR
Retrieves stored data (this function is independent of the selector setting of the
switch) except for the OFF and SET-UP positions. Data is viewed using the
▲ and ► buttons. The , and ALARM buttons can be used.
Turns the display backlight ON or OFF.
Activates or deactivates the buzzer and adjusts the sound level.
