ACL 880 Operation Manual
Be aware that other leads may not provide similar performance and will require
recalibration of the Null point to improve measurement accuracy.
Always use supplied leads for best performance. Lead quality and length affect
instrument accuracy. This is due to several factors such as insulation resistance, lead
inductance and capacitance, as well as transmitted "noise" in the environment. To
minimize the effect of noise and transmitted energy on measurement accuracy, the
black sensing lead is shielded. Long 200 cm leads are supplied for auditing purposes
where lead length is physically necessary. Long leads will allow the instrument to
perform within its targeted performance.
RECOMMENDED USAGE
ACL 880 instruments and fixtures shall be operated at 65 – 90° Fahrenheit (18 – 32° Celsius), 10
– 60 % Relative Humidity. ACL 880 recommends making measurements using its instruments
and fixtures in an environment of 72 – 76° Fahrenheit (22 – 24° Celsius), 25 – 35% Relative
Humidity.
MODES OF OPERATION
1. Install leads and slide main power switch to ON. Wait for "GO A" to appear in display.
AUTO mode (GO A) is the default operation mode. To switch to MANUAL mode (GO C),
press the MODE pad and TEST pad simultaneously.
2. When using AUTO mode (GO A), the resistance range, test voltage and electrification
period (EP) is automatically adjusted according to standard measuring protocol. See
below for more information regarding EP. MANUAL MODE can be selected if a
measurement is to be taken at a specific test voltage.
a. To start measurement in GO A, press & release TEST pad. Measurement
sequence is conducted automatically and ends when green HOLD LED
illuminates. Yellow LED lights correspond to the voltage applied.
b. Final measurement is displayed for 10 seconds then instrument resets for the
next measurement.
c. Use the MODE button to interrupt or clear measurement.
d. Press TEST to restart the measurement.
3. When using CONTINUOUS mode (GO C), the resistance range and test voltage are
automatically adjusted according to standard measuring protocol. , The electrification
period (EP) is disabled. See below regarding more information on EP. MANUAL MODE
can be selected if a measurement is to be taken at a specific test voltage.
a. To switch from GO A to GO C, press MODE pad and TEST pad simultaneously.
