HOLD mode.

Note: Although the display is frozen, internally the meter continues

measuring and updating Hi/Lo and relative values.

In HI 935009 only, the held value is also stored in non-volatile

memory and can be recalled by pressing (ALT+) MR key. While the

MR key is held, the "HOLD" tag lights up and the meter displays the

stored value; when the MR key is released, after 1 second the meter

returns to normal measurement mode.

HIGH/LOW TEMPERATURES

The maximum and minimum tempera-

tures are continuously monitored and

displayed on the lower portion of the LCD.

Note: When the reading goes over-range

or the probe is removed, the Hi and

Lo values display dashes until cleared.

CLEAR FUNCTION

Upon pressing the CLR key, the High/Low values may be cleared at

any time during measurement and the current reading is assigned to

the highest and lowest temperature values for the displayed channel

only.

AUTO SHUT-OFF (HI 935005 and HI 935009)

To save battery life, the HI 935005 and HI 935009 models are

provided with an auto-off feature, which switches the instrument off

after a certain period of nonuse.

The delay time can be changed by the user (8 minutes, 60 minutes,

or disabled).

To access this feature, the HI 935005 is provided with an internal

button located in the battery compartment (see figure on page 10).

Unscrew the 4 screws on the back of the meter and select the desired

auto-off time period by pressing the button and viewing the value on

the LCD. Re-attach the back making sure that the gasket is in place

and tighten the 4 screws to ensure a watertight seal.
