Battery Installation & Replacement

1. If installed, remove the protective boot.

2. Remove the battery cover from the rear of the BluVac+ LTE by compressing tab at the base of

the battery cover.

3. If necessary, remove and detach old battery from battery clip.

4. Attach battery clip to new battery and insert into battery compartment. Replace battery cover by

aligning tab and snapping back into place.

5. Reinstall the protective boot.

IMPORTANT: TO PREVENT DAMAGE FROM LEAKING BATTERIES, DO NOT LEAVE A DEAD

BATTERY INSIDE THE BluVac+ LTE. REMOVE BATTERY IF THE BluVac+ LTE IS NOT TO BE

USED FOR AN EXTENDED PERIOD OF TIME.

Battery Level Indicator

The battery level indicator shows the relative strength of the battery. Four bars indicate full power.

As the battery is depleted, the number of bars displayed decreases, until no bars are left. At this

point, it is necessary to replace the batteries (refer to the Battery Installation section above). If the

battery power drops to the point where the BluVac+ LTE can no longer function accurately, the alarm

will beep 10 times and the power will turn off automatically. When the battery is replaced, and the

BluVac+ LTE is turned back on, the BluVac+ LTE will resume operation with all previous settings

intact.

Hi-Pressure Indication

If the sensed vacuum pressure exceeds 25,000 Microns (3333.1 Pa, 33.331 mBar, 25,000 mTorr, or

25.000 mmHg), the display will show .

Units

Change the displayed units by pressing the key on the keypad. The appropriate units indicator

on the LCD display will show Pa, mBar, mTorr, mmHg, or Microns depending on the units set.

Sleep Mode

Unlike other Digital Vacuum Gauges, the BluVac+ LTE helps to conserve battery life through

advanced power management. After 5 minutes of displaying , the BluVac+ LTE will enter “Sleep

Mode” in which the sensor and backlight are turned off, thus reducing the load on the battery and

extending the battery life up to 300 hours or more. While in this mode, the display will show .

Approximately every 35 seconds, the gauge will automatically check the pressure and exit Sleep

Mode if the pressure is less than 25,000 Microns. The gauge can be manually brought out of Sleep

Mode by pressing any key on the keypad. While in Sleep, the gauge will beep twice every 5 minutes

to remind you that it is on. The BluVac+ LTE will not sleep in the Calibration Mode (see the

Calibration section below), or if the wireless function is activated and a connection is active.

Auto Power-Off

After 1 hour in “Sleep Mode” the BluVac+ LTE will automatically turn itself off to further conserve

battery power.
