#%NAME%
# Use the keithley 2001 multimeter as a pseudo-counter
# (Obsolete: use multim.mac instead)
#
#%CATEGORY% Detection, Multimeter, Obsolete
#
#%DESCRIPTION%
# The keithley 2001 multimeter can be used as a counter . Each time you
# ask spec to count it will look for counters with a name
# k_<keithley_number>_<channel_number> for multiplexed use or
# k_<keithley_number> without multiplexing and read it once.
# The keithley will be programmed to automatic scaling.
#%EXAMPLE%
# counter k_1_1 and k_1_2 have been configured with spec
# configuration editor.
#%DL%
# %DT% k2001setup 10 1 1 2 %DD%
# You set up two multiplexed entries on one keithley on gpib address 10
# %DT% ct 2 %DD%
# The actual values in the multimeter will be read on multiplexed
# entry 1 and 2 and put into the counters k_1_1 and k_1_2.
# The 2 will not have any meaning if you did not configure another
# counter. The keithley will be read only once.
# %DT% ascan m1 0 10 1 1 %DD%
# The motor m1 will be scanned and the to entries will be read at
# each point.
