SETUP MODE
Note
This procedure adjusts the meter’s
internal clock. The internal clock will
function when the meter is turned off
but only when the batteries have
adequate power (not with low battery
power.)
Sampling Time
The sampling time (hour/minute/
second) is the time allotted between
successive measurements. To adjust
the sampling time:
1. Enter the sampling time function
from Setup Mode (see page 13).
“SP-t” appears on the LCD.
2. Press ▲ or ▼ to adjust the value
(starting with the hour value).
Press ENTER to save the value.
The meter will advance to the next
value adjustment (minute,
second).
3. Repeat Step 2 until the setting is
complete.
