Enable and Disable of Auto Ranging Functions of F and Cx (Capacitance
Measurements):
Rotary Switch points to the positions F or Cx. Press this button to disable Auto Range and
change to next Range. Press and hold down the button for 2 second to enable of Auto Range.
6.1.8 “Shift” --- Shift Mode
In “Normal Mode”, press this button to enter to enter “Shift Mode”. In “Shift Mode”, press
this button to exit “Shift Mode” and return to “Normal Mode”.
6.2 Shift Mode
Press “Shift” button in “Normal Mode” to enter “Shift Mode”.
An annunciator “
S
” shows at lower-right part of LCD to indicate the push button is now
working in the shift mode.
Functions of push buttons in “Shift Mode” are printed in yellow color above each button. To
leave “Shift Mode” just press the “Shift” button again or change position of the Rotary Switch
(The annunciator “
S
” disappears.).
6.2.1 APO Enable and Disable “Auto Power Off” Function
When APO (Auto Power Off) is enabled, power is automatically turn off if no operation for a
period of time (factory setting = 10 min. can be reset by user). After APO, power can be
restored by turning the rotary switch.
In “Shift” Mode, press “APO” button to enable or disable “Auto-Power-Off” function. When
“Auto-Power-Off” function is enabled the annunciator “APO” shows at the upper-left corner
of LCD. Remember to press “Shift” button to leave the “Shift Mode” and return to “Normal
Mode”.
APO function will be disabled as follow:
1. External power is used.
2. RS-232 function is used.
3. MAX, MIN, MAX-MIN, AVG function is used.
4. Data logger function is used.
6.2.2 SETUP
In “Shift Mode”, press “SETUP” button to change the operation mode into “Set Up” Mode.
Press “Shift” button to leave “Set-Up” mode and return to “Normal Mode”. Please refer to
