Getting to know your TW-1
Your TW-1 is a quality, precision instrument that will give you many years of outstanding
service; take a few minutes to get to know it. On the front panel, there is a volume knob and three
pushbuttons:
• Volume: adjusts the volume of the synthesized voice
• Forward: measures forward power in watts (FWD Button)
• Reverse: measures reverse power in watts (REV Button)
• SWR: measures the standing wave ratio (SWR Button)
Readout resolution is 1 watt or 1% of the reading, whichever is larger. For example, if the reading
is 75 watts, 1% would be 0.75 watts, so the achieved resolution would be 1 watt. The readout
would go from "Seventy Five Watts" to "Seventy Six Watts" as you increase power. At a reading
of 245 watts, 1% would be 2 watts (rounded off), so the resolution would be 2 watts; the reading
would go from "Two Hundred Forty Five Watts" to "Two Hundred Forty Seven Watts".
There is no range switch; the TW-1 auto-ranges from 0 to 2,000 watts. There is no On/Off switch;
the TW-1 automatically turns itself on during use and off after use. The idle current is less than
100 uA.
