Differential measurement; resolution for single-ended measurement is twice value shown.
NOTE: When a voltage input exceeds the range programmed, the value which is stored is set to the
maximum negative number and displayed as -99999 in high resolution or -6999 in low resolution.
*** 1 SINGLE-ENDED VOLTS ***
FUNCTION
This Instruction is used to measure voltage at a
single-ended input with respect to ground.
Output is in millivolts.

*Repetitions for the input/output instructions are
limited to two differential or four single ended
measurements.
*** 2 DIFFERENTIAL VOLTS ***
FUNCTION
This Instruction reads the voltage difference
between the high and low inputs of a differential
channel. Table 9-1 contains all valid voltage
ranges and their codes. Both the high and low
inputs must be within ±2.5 V of the CR510's
ground (see Common Mode Range in Section
14.7.2). Pyranometer and thermopile sensors
require a jumper between LO and GROUND to
keep them in Common Mode Range. Output is
in millivolts.

*** 3 PULSE COUNT ***
There are three pulse input types which may be
measured with the Pulse Count Instruction. The
Pulse Count Instruction may also be used to
measure switch closures (<40 Hz ) with Control
Port C2 see Section 8.5 for examples).
HIGH FREQUENCY PULSE
In this configuration, the minimum detectable
pulse width is 2 microseconds, i.e. the
maximum frequency is 250 kHz with a 50% duty
cycle. The 8 bit counter has a maximum input
frequency of 2000 Hz and the 16 bit option a
maximum of 250 kHz. The count is incremented
when input voltage changes from below 1.5
