6 HOLD Function

This feature lets you freeze the display for a delayed observation. HOLD can be
used in any measurement mode.
1. To hold a measurement, press the HOLD/ENTER key while in

measurement mode. The %, mg/L, ppm or T annunciator in the display
will start blinking to indicate that the measurement is being held.

2. To release the held value, press the HOLD/ENTER again. The

annunciator will stop blinking to indicate that the held value has been
released.

3. Continue to take measurements.

Note: This meter has a selectable auto off feature which when activated will
shut the meter off automatically after 20 minutes of non use.
If the meter is shut off either automatically or manually, the HOLD value will
be lost.
