FUNC	Channel Function Definition
	Define the Changing a channel configuration automatically erases values held in
	review, and resets all ALARM OUTPUTS and DIGITAL I/O lines to logical high. The
	FUNC command clears any alarm limits and scaling values for this channel;
	therefore, define a channel function before setting alarm limits and/or scaling values
	for that channel. measurement function and range for the indicated channel.
	FUNC	<channel>, <function>, <range>, <terminals>
		<channel> = 0, 1,2, ...20
		<function> = OFF, VDC, VAC, OHMS, FREQ, TEMP
		<range> = 1,2,3,...6, AUTO [VDC, VAC,OHMS, FREQ]
		<range> = J, K, E, T, N, R, S, B, C [TEMP with thermocouples]
		<range> = PT [TEMP with RTDs]
		<terminals> = 2 or 4
	Ohms and temperature measurements that use a 4-terminal configuration are limited
	to channels 1 to 10. Select a channel function, OFF, VDC, VAC, OHMS, FREQ, or
	TEMP. For voltage, ohms or frequency, select a range 1 to 6, as specified in the
	table below (or AUTO for autoranging) For temperature, select a thermocouple type,
	or PT for RTDs.
	RANGE		VOLTAGE	OHMS	FREQUENCY
	1		300 mV	300 e	900 HZ
	2		3 V	3 ke	9 kHz
	3		30 V	30 ke	90 kHz
	4		150/300 V*	300 ke	900 kHz
	5		90 mV**	3 Me	1 Mhz
	6		900 mV**	10 Me

*300V only on channels 0, 1, and 11

** Volts DC only

The <terminals> selection is specified only when the function type is OHMS, or TEMP using an RTD. The 2-terminal selection is valid on any channel. The 4- terminal selection is valid only for channels 1 to 10 (n), which automatically clears a channel a decade higher (n+10).

Example: FUNC 9,TEMP, PT,2 [Set the function of channel 9 to temperature measurements using a Platinum RTD, and the 2-terminal connection.] Example: FUNC 5,VDC,4 [Set the function of channel 5 to volts DC, and use the 150V scale.]
