Annunciators:
LCD annunciators for all ranges, functions and program modes.
Reading Rate:
Varies with function, selectable between 4 SPS and 20 SPS.
Overrange:
Displays OFL if input too great for range.
Overflow:
Displays -Or- if calculated result overflows display.
COMPUTING FUNCTIONS
Null (Relative)
Stores current reading and subtracts it from future readings.
Ω Null:
Additional non-volatile function for nulling test lead resistance.
Hold:
Reading is frozen
T-Hold (Touch & Hold):
Reading is frozen when stable.
dB:
Displays measurement in dBm relative to 600Ω or other user-entered
impedance.
AC plus DC:
The RMS value of the ac plus dc parts of the signal is calculated and
displayed.
% Deviation:
Displays % deviation from entered reference value.
Ax+b:
Linear scaling of results, with offset.
Limits:
Reading displayed with HI, LO, or PASS with respect to user-defined
high and low limits.
Min/Max:
Minimum and maximum reading stored.
Power:
Calculates V
2
/R and displays in Watts with respect to a user-defined
impedance.
VA:
