To Read the Totalizer Count

The multifunction module (34907A) has a 26-bit totalizer which can

count pulses at a 100 kHz rate. You can manually read the totalizer

count or you can configure a scan to read the count.

Select the slot containing the multifunction module and continue turning

the knob until TOTALIZE is displayed (channel 03).

2 Configure the totalize mode.

The internal count starts as soon as you turn on the instrument. You can

configure the totalizer to reset the count to “0” after being read or it can

count continuously and be manually reset.

3 Read the count.

The count is read once each time you press ; the count does not

update automatically on the display. As configured in this example, the

count is automatically reset to “0” each time you read it.

The count will be displayed until you press another key, turn the knob,

or until the display times out. To manually reset the totalizer count,
