Data Hold

Warning
To prevent possible electrical shock, fire or
personal injury, do not use the HOLD function
to measure unknown potentials. When HOLD
is turned on, the display does not change
when a different potential is measured.
To hold the present reading, push
to resume normal operation.

Relative Measurements (17B+ only)

The Product allows relative measurements for all functions
except frequency, resistance, continuity, duty cycle, and
diode.
To do relative measurements:
1. With the Product in the desired function, touch the
test leads to the circuit on which you want future
measurements to be based.
2. Push  to store the measured reading as the
reference value and activate the relative
measurement mode.

. Push again
The difference between the reference value and
subsequent reading shows on the display.
3. Push  for to return to normal operation.

MIN MAX Mode (17B+ Only)

To set the Product to MIN MAX mode (available for all
functions except resistance, capacitance, frequency, duty
cycle, and diode):
1. Push  once to set the Product to MAX mode.
2. Push  again to set the Product to MIN mode.
3. Push  for 2 seconds to return to normal operation.
