Hi / Lo Limits Mode
The Hi / Lo limits mode compares the measured value to the stored high and low limit values and
gives an audible and visible indication if the measured value is outside the limits. See the setting
Hi/Lo limits paragraph below to store the limits in memory.
1. Press
the
Hi/Lo LIMITS
key to enter the mode. The display will briefly show the stored upper
limit with the “ “ indicator and then the stored lower limit with the “ “ indicator before
displaying the measured value.
2. The meter will sound an audible tone and blink the upper or lower limit indicator if the
measured value is outside the limits.
3. The meter will ignore an “OL” overload reading.
4. Press the Hi/Lo LIMITS key to exit the mode.
% Tolerance Mode
The % Tolerance Limits mode compares the measured value to a % high and low limit based on a
stored reference value and gives an audible and visible indication if the measured value is outside
the limits. Any % limit can be entered in the SET % Limit mode (see paragraph below) or standard
1%, 5%, 10% and 20% symmetrical limits can be selected directly in the % Tolerance mode.
1. Press
the
TOL
key to enter the mode. The display will briefly show the stored reference value
in the main display and the small display will indicate the % difference between the measured
value and the reference value. See the SET % Limit paragraph to change the reference
value.
2. Press the TOL key to step through and select the 1, 5, 10 or 20% settings. The selected %
will briefly appear in the small display.
3. Previously stored user defined % limits are accessed by pressing the SET key.
4. The meter will sound an audible tone and blink the upper or lower limit indicator if the
measured value is outside the limits.
5. Press and hold the TOL key for 2 seconds to exit the mode.
Set Limits and Open/Short Calibration Selection
The
SET
key is used to; 1. Set Hi/Lo limits, 2. Set % limits, 3. Set Tolerance reference value and 4.
Perform the Open / Short calibration. The SET mode can only be activated if no other function is
active.
Entering the SET mode
1. Power ON and press the
SET
key.
2. The display will clear, “
SEt
“ will appear in the small display and a flashing
TOL
and flashing
indicators will appear in the display.
3. The 5 keys that are now active are; Power, SET, REL, Hi/Lo, and TOL
Open and Short Calibration
The Open and Short function removes stray parallel and series fixture impedances from the
measured value. This feature improves accuracy for very high or low impedances.
(Note: Remove any leads from the meter during this procedure. Leaving them connected will add
impedance to the circuit causing the calibration to fail indicated by
OUT UAL
appearing on the
display.)
1. Press
the
SET
key 2 times and the display will indicate “
CAL OPEn
”.
2. Remove any devices or test leads from the input terminals and press “ENTER” (PAL SER).
After several seconds the calibration will complete and display “
CAL SHrt
”.
3. Short the input terminals and press “ENTER” (PAL SER). After several seconds the
calibration will complete and the meter will return to normal operation.
4. Press the “SET” to bypass either the open or short calibration.
