4. Prenotion

Danger

z To avoid electrical shock and

personal injury, please don’t
measure the source out of
specification.

z The maximum AC voltage is 125V

rms or 175V peak, 100kHz, 1A
switched 62.5VA (resistive load),
and DC voltage is 110V, 1A
switched, 30VA (resistive load).

Warning

z To avoid breaking the product,

please do not pull it away when
measurement is executed.

Ask the state. The state 1 means Card

inserted or 0 means Card not i nserted.

Set card states which might measue

the VAC, VDC, Frequency, 2-Wire

Resistance, 4-Wire Resistance or

disabling the channel.

Ask the channel’s state of the card.

Set the time interval of scanning <The

unit is second>.

Set the number of times of scanning.

Read the state of scanning. 1 means

“finished”. 0 means “not finished”.
