71 – Setup metering. This function lets you configure the metering modes and values and you must be on the
channel to be programmed. In every case, you must select either the normal setup (Mode 1) or if you will be entering
meter voltages manually (mode 2). Most metering setup, except for direct reading VSWR will be done using the standard
method. See “two ways to setup metering“ below for more info on the manual method. You should also review the
metering setup quick reference below. NOTE: There is a temporary limitation on decimal points when calibrating.
Decimal points had to be removed to make space for other functions. Please see the note on page 41 for more info.
When entering the meter setup mode you have five initial options:
0 = Linear metering mode. (this mode is direct reading without scaling- Like a talking Voltmeter)
1 = Linear with “scaling” metering mode. This is the most common metering mode. (meter Val x scaler value)
2 = Reserved for future
3 = Power mode. For reading power meters. (meter value x meter value x scaler factor) This is the second most
common type of metering mode, but many “power” meters are actually linear or log meters. If the readings don’t track, try
changing to linear or log mode.
4 = Log scale mode (meter value x log20 x scaler value)
5 = Indirect Calculation. This mode uses two metering inputs and a multiplier to calculate a value. Indirect mode is commonly
used to calculate a radio or TV station’s operating power as specified in the license. One channel must be the currently selected
channel. You must provide an input sample to the channel for the Sicon-8 to use. For instance, if you have transmitter plate Voltage
on meter # 1 and Plate current on meter #2 and you want to calculate the indirect power for channel 3, you must parallel either the
plate Voltage or the plate current sample to the currently selected metering channel (channel 3). The Sicon-8 will be multiplying the
current metering channel input with the other channel and applying a scaling factor to calculate the reading.
Setup: Sicon-8 beeps once. Choose the
units identifier by selecting 0 to 9.
Sicon
beeps twice.
Setup is identical to “Linear with Scaling above: The Sicon-8 beeps once. Enter a 1 to proceed with normal setup
or a 2 for manual setup & see “Two ways…” below. If performing a normal setup, enter actual value of the
physical meter (the appropriate meter on the transmitter) that is associated with this channel. The Asterisk (*)
places a decimal. Use the # key to end the entry. The Sicon-8 speaks the value that you entered back. Press 1
to confirm or 0 to re-enter. The Sicon-8 will take a sample reading, AutoScale its meter and then beep once.
Choose the units identifier by selecting 0-9. The Sicon-8 beeps twice indicating completion of that metering
channel setup.

Indirect Setup: The Sicon-8 beeps once. Enter a 1 to proceed with standard metering setup or see “Two ways…” below.
Enter the meter type (5). Enter the two digit channel number that the Sicon-8 will use for the multiplier. The Sicon-8 will
then beep once. Enter the value of the meter connected to the current channel. The Asterisk (*) places a decimal. Use
