substituted for the input frequency. The Flow Indicator is in all other respects essentially in

the RATE mode. All readings in the TEST mode must be exact.

1.1.2.6

REMOTE

This position of the function switch transfers control of the mode, thumbswitch and multiplier

selection to external means through the REMOTE Connector. All selections are made by

either contact closures or TTL/DTL logic "0", i.e.+0.4 V max. current sinking, two TTL loads

max.
