Notes regarding Lithium Batteries

WARNING: The batteries in this meter must be discharged to 1/3 or less capacity before

the unit can be transported by Air. This is a legal and safety requirement for all lithium batteries.

WARNING: The internal batteries are not user serviceable. The meter must be returned

to Telewave for service if the batteries no longer accept or retain a sufficient charge.

Telewave recommends returning the wattmeter to the factory every two years for inspection &

calibration. Calibration must be done at Telewave, contact Telewave sales for a quote.

The inspection includes checking the health of the batteries and creating a battery health report.

To return a meter to Telewave; complete the RMA request form located on our web site

www.telewave.com, or call 408-929-4400 Option 1 if assistance is needed to compete the RMA.

Operation

Charging Power Supply & International Power Adapters

The included power supply for charging the batteries supports 90 to 250 volts at 50 or 60 hertz.

The power plug on the power supply is an IEC international “Plug Type A”.

Type A to Type C, G, and I adapters are included with the wattmeter. This AC adapter kit will

allow the power supply to be safely connected to the power sockets in most countries.

Visit the International Electro technical Commission (IEC) website for a complete list of socket

types, and power voltage/frequencies used in various countries: http://www.iec.ch/worldplugs/.

Charging the Battery

The battery can be charged when the meter is on or off, and can be charged from any USB

source that supports a 2.4 amp load (laptop USB port, vehicle charging adapter, etc.) Connect

the supplied USB cable between the power source and the meter, charging will begin as soon as

the meter detects voltage on the USB connector.

CAUTION: When the meter off the display is blank. There is no indication that the meter

is charging, fully charged, or that the USB cable is disconnected or not suppling charge current.

Battery charge indication:

Bars 3 equals >3/4, 6-8 hours awake time remain

Bars 2 equals >1/2, 4-6 hours awake time remain

Bars 1 equals >1/4, 2-4 hours awake time remain

Flashing equals <1/4, 0-2 hours awake time remain

Though not recommended, the wattmeter can be left connected to the USB power source for an

extended period of time. The internal charging controller can detect when the batteries are fully

charged, and stop charging the batteries until they have been partially discharged.

WARNING: Charge the batteries at least once every six months to prevent battery damage

CAUTION: Fully charge the batteries after removing the meter from long term storage.

Power Control

The meter has a latching push power button in the lower left corner of the front panel.

To turn the meter ON, push the power button until you hear a clicking sound and/or you see that

the power switch rim is illuminated with a blue glow. After a few seconds the display backlight

will illuminate, and the power up sequence will be shown in the display.

The power up sequence, as is seen in the display is:

The screen backlight will illuminate after about two seconds

Then the HOME screen will display

After that the frequency, temperature and battery status indications will be displayed

Once the power up sequence is complete the HOME screen will indicate the settings that were

selected when the meter was previously turned off (units of measurement, backlight level, etc.)

The power switch will remain partially depressed while the meter is turned on.

To turn the meter OFF, push the power button in slightly further, and release. The switch will

return to the flush position, the blue rim light will extinguish, the display backlight will turn off

and the display will become blank. There are no lights or display activity when the unit is off.

Sleep Mode

The meter can be configured to go to “sleep” after few of minutes of inactivity. Inactivity is

defined as no function select buttons have been pushed. If the meter is connected to a transmitter

and is reading power, it will still go to sleep if the sleep timer expires (no buttons were pushed.)

Sleep mode is indicated by the following:

The display backlight will extinguish and the display will be blank/dark

The meter will emit a beep sound as it is going to sleep

The blue ring around power button will remain lit

To wake the meter, turn off the power button and then turn it back on.

The meter will boot back to the previous configuration in a few seconds.

CAUTION: The meter will only go into sleep mode when the HOME screen is displayed.

When any screen other than HOME is displayed and the sleep timer expires, the meter will wait

for the user to complete the pending action; and then go to sleep.

NOTE: RF signals will flow though the through line sensor un-impeded with the wattmeter

power turned on or off. Any live circuits that are monitored with the wattmeter will not be

affected if the wattmeter goes to sleep or is turned off while connected to the circuit.
