Operation Guide 3070

3. To stop an ongoing save session, hold down A for about one second until REC disappears from the screen.

The save session also will stop automatically when Periodic Record 40 is stored.

The watch updates the historical record continually while an altitude measurement operation is in progress. See “Historical Record” for more information.

You can recall saved records using the Data Recall Mode.

Periodic Records

Periodic records of up to 40 altitude readings are taken during a save session.

You can use the Data Recall Mode to view these records.

How periodic records are created and saved

Note

The following operation is performed simultaneously with the operation described under “How current session record data is updated”.

a.The watch creates Periodic Record 1 when you start a new save session. Periodic Record 1 contains the current date (month and day), time, and altitude.

Each periodic record contains the current date (month and day), time, and altitude.

b.After that, the watch takes readings and stores Periodic Records 2, 3, 4, and so on at minute 00, 15, 30, and 45 of each hour.

c.After Periodic Record 40 is stored (or if you stop the save session manually by holding down A), the watch will create a final periodic record, which contains the current date (month and day), time, and altitude.

Current Session Record

The Current Session Record contains the data described below. The contents of this record are updated at regular intervals while a save session is in progress.

Data

Description

High Altitude

Highest altitude reached during the current session.

(MAX)

 

Low Altitude

Lowest altitude reached during the current session.

(MIN)

 

Total Ascent

Total cumulative ascent during the current session.

(ASC)

 

Total Descent

Total cumulative descent during the current session.

(DSC)

 

The maximum total ascent and total descent value is 99,995 meters

(or 99,980 feet). Each value reverts to zero after the maximum is reached.

How current session record data is updated

Note

The following operation is performed simultaneously with the operation described under “How periodic records are created and saved”.

a.When you hold down A to start a save session, the watch will clear data that is already stored in the current session record.

b.The watch will measure altitude and calculate data as described below, and update the current session record accordingly. Note that measurement and saves depend on whether or not the watch is in the Altimeter Mode.

Historical Record

The Historical Record keeps track of high altitude, low altitude, total ascent, and total descent values across multiple save sessions. The contents of this record are updated continually while an altitude measurement operation is in progress.

How the historical record is updated

The watch performs the following operations continually while an altitude measurement is in progress.

Data

Update Operation

High Altitude

The historical record value is compared with the current

session value, and the greater of the two is recorded in

 

 

the historical record.

Low Altitude

The historical record value is compared with the current

session value, and the lesser of the two is recorded in the

 

 

historical record.

Total Ascent

The current session value is added to the historical

 

record value.

Total Descent

 

 

 

See “Clearing the Historical Record” for information about clearing the historical record, which restarts all data values from zero.

Other Altimeter Mode Features

This section explains other features and settings that are available in the Altimeter Mode. Note that all of the information in this section applies to all types of Altimeter Mode measurements, unless specifically indicated otherwise.

Specifying a Reference Altitude

After you specify a reference altitude, the watch adjusts its air-pressure-to- altitude conversion calculation accordingly. The altitude measurements produced by this watch are subject to error caused by changes in air pressure. Because of this, we recommend that you update the reference altitude whenever one is available during your climb.

To set a reference altitude

 

 

 

 

 

 

 

 

 

 

1. In the Altimeter Mode, hold down E for about

reference altitude value by 5 meters (or 20 feet).

 

 

 

 

 

 

 

You can set the reference altitude within the range of –10,000 to 10,000 meters (–32,800 to 32,800 feet).

Pressing A and C at the same time returns to OFF (no reference altitude), so the watch performs air pressure to altitude conversions based on preset data only.

3. Press E to exit the setting screen.

Altitude graph

 

The altitude graph shows Altimeter Mode

Altitude

measurement results.

The vertical axis of the graph represents

 

 

altitude, and each dot stands for 10 meters (40

Timefeet).

The horizontal axis represents time, and the flashing dot in the rightmost column indicates the latest measurement result. For the first three minutes, each dot represents five seconds. After that, each dot represents two minutes.

An out of range measurement result or a measurement error will cause the column of dots for that measurement to be blank (skipped).

Altitude Differential

You also can use the Altimeter Mode to measure the altitude differential from a specific reference altitude. Specifying the point is as simple as pressing a single button to reset the current reference altitude value to zero. Altitude differential measurement is performed each time the watch performs an altitude measurement.

You must perform altitude differential measurement whenever you select format number 3 or 4 as the Altimeter Mode display format.

The range of the altitude differential value is –3,000 meters (–9,980 feet) to 3,000 meters (9,980 feet).

------ is displayed in place of the altitude differential value whenever the measured value is outside the allowable range.

The watch will assume that the reference altitude setting is zero for the first measurement after you exit the Altimeter Mode setting screen.

See “Using Altitude Differential Measurement While Mountain Climbing or Hiking” for some real-life examples of how to use this feature.

To reset the altitude differential value to zero

In the Altimeter Mode, press E.

This will start altitude measurement. The

Using Altitude Differential Measurement While Mountain Climbing or Hiking

After you zero reset the reference altitude value at a particular location while mountain climbing or hiking, you easily can measure the change in the altitude between that point and another point.

To use altitude differential measurement

 

1. In the Altimeter Mode, check to make sure

Destination

that the display shows the altitude differential

value.

If the altitude differential value is not displayed, use the procedure under “To select an Altimeter Mode display format” to select display format 3 or 4.

2.Use the contour lines on your map to determine the difference in altitude between
