Startup Calibration - Tandem T:Slim X2 User Manual

Make sure the antenna symbol is
•
visible to the right of the battery
indicator on the CGM Home Screen
and is active (white, not greyed out)
before calibrating.
Always use the same meter to
•
calibrate that you routinely use
to measure your blood glucose.
Do not switch your meter in the
middle of a sensor session. Blood
glucose meter and strip accuracy
vary between blood glucose meter
brands.
The accuracy of the blood glucose
•
meter used for calibration may affect
the accuracy of sensor glucose
readings. Follow your blood glucose
meter manufacturer's instructions for
blood glucose testing.

23.2 Startup Calibration

2 hours after you start the sensor
session, the CALIBRATE CGM screen
will appear, letting you know that 2 sep-
arate blood glucose values from your
meter must be entered. You will not see
sensor glucose readings until the pump
accepts the blood glucose values.
1. From the Calibrate CGM Screen,
Tap CLOSE.
2. The CGM Home Screen will
appear with two blood drops
in the upper right portion of the
screen. The two blood drops will
stay on the screen until you enter
2 separate blood glucose values
to calibrate.
3. Wash and dry your hands, make
sure your glucose test strips
are not expired and have been
stored properly, and make sure
your meter is properly coded (if
required).
4. Take a blood glucose
measurement using your meter.
Carefully apply the blood sample
to the test strip following your
meter manufacturer's instructions.
PRECAUTION
DO NOT use alternative blood glucose site
testing (blood from your palm or forearm,
etc.) for calibration. Alternative site blood
glucose values may be different than those
taken from a fingerstick blood glucose
value and may not represent the timeliest
blood glucose value. Use a blood glucose
value taken only from a fingerstick for
calibration. Alternative site blood glucose
values might affect sensor accuracy and
result in you missing severe hypoglycemia
(low blood glucose) or hyperglycemia (high
blood glucose) events.
