10. ADDITIONAL FUNCTIONS

The function buttons (2) can be used to activate various additional functions.
With the button function activated, an acoustic signal is output for confirma-
tion. If no sound is output, this additional function is not available in the current
measuring function.
a) MODE Function
Several measuring functions are assigned subfunctions. Push "MODE" to select them. Every push will switch to the
next subfunction. All dial switch ranges (except for V
b) Manual Measurement Range Selection "RANGE"
The RANGE function permits manual setting of a specific measurement range. It is possible that the automatic meas-
urement range setting will already select the next-higher measurement range or switch between ranges if the range
is problematic. To suppress this, the measurement range can be set manually in some measuring functions. The
manual measurement range setting works only in the following measuring functions: µA, mA, A, V, mV, Ω and Temp.
Pushing the "RANGE" button will cause the "AUTO" symbol to go out and the device to switch to manual mode.
Each push of the "RANGE" button switches the measurement range; at the end, it will start with the lowest measure-
ment range again. The respective measurement range is indicated by the position of the decimal point.
To switch off this function, keep the "RANGE" button pressed for approx. 2 s. The "AUTO" symbol appears and the auto-
matic measurement range selection is active again. Switching the measuring function deactivates this function as well.
c) MAX MIN Function
This function permits saving and display of maximum or minimum values during a measuring series. Press the "MAX
MIN" button to activate this measuring function. Auto-range is deactivated.
With the active function, the minimum and maximum value of the current measuring series is saved at the same time.
The max. and min. display can be switched at every push of a button. The values are deleted after a measuring func-
tion change or when switching off the device.
To deactivate the function, keep the "MAX MIN" button pushed for approx. 2 seconds. The display "MAX" or "MIN"
disappears and "AUTO" appears again.
d) REL∆ Function
The REL function allows a reference value measurement to avoid possible scatter displays or line loss as it occurs,
e.g., during impedance measurements. For this purpose, the current indicated value is set to zero. A new reference
value is set. Auto-range is deactivated.
Press the "REL" button to activate this measuring function. The display indicates "REL". The automatic measurement
range selection is deactivated now (except for capacity measurement range).
In order to switch off this function, push the "REL" button again or change the measurement function.
The REL function is not active in the frequency measurement range, during diode tests and conti-
nuity tests.
